So, grab your sewing machine, your favorite fabric, and let's get started on this step-by-step tutorial!

Materials You'll Need

Before we jump into the sewing process, let's gather all the materials you'll need for your DIY tank top. Having everything ready will make the process smooth and enjoyable. Here's a comprehensive list to get you started:

Fabric: Choosing the right fabric is crucial for the look and feel of your tank top. Look for lightweight, breathable fabrics like cotton, linen, rayon, or jersey knit. These materials are comfortable to wear, especially during warmer months. Consider the stretch and drape of the fabric as well. Knit fabrics offer more stretch, making them ideal for a fitted tank top, while woven fabrics provide a more structured look. For a beginner-friendly option, a medium-weight cotton or cotton blend is a great choice. You'll need about 1-2 yards of fabric, depending on your size and the pattern you're using. Always pre-wash your fabric to prevent shrinkage after sewing your tank top.
Sewing Machine: A reliable sewing machine is the heart of any sewing project. If you're new to sewing, a basic machine with adjustable stitch length and width will work perfectly. Ensure your machine is in good working order, with a fresh needle appropriate for your fabric type. Practice sewing on scrap fabric before starting your project to get a feel for your machine and make any necessary adjustments. If you don't own a sewing machine, consider borrowing one from a friend or family member, or renting one from a local sewing shop or maker space. Familiarize yourself with the machine's manual to understand its features and capabilities.
Scissors or Rotary Cutter: Sharp fabric scissors are essential for accurately cutting your fabric pieces. A rotary cutter, used with a cutting mat, can also be a great tool for cutting straight lines and curves with precision. Invest in a good quality pair of fabric scissors that are specifically designed for cutting fabric to ensure clean, even cuts. Avoid using your fabric scissors for paper or other materials, as this can dull the blades. Regularly sharpen your scissors to maintain their cutting ability. If you opt for a rotary cutter, remember to use a self-healing cutting mat to protect your work surface and extend the life of the blade.
Pins: Straight pins are used to hold fabric pieces together before sewing. Choose pins with rounded heads that are easy to grasp and won't snag your fabric. Pin your fabric pieces perpendicular to the seam line, about every 2-3 inches, to prevent shifting while sewing. Be careful not to sew over pins, as this can damage your sewing machine needle. Remove the pins as you sew, or use magnetic pin cushions to keep them organized and prevent accidents. Consider using different types of pins for various fabrics; for example, fine pins are best for delicate fabrics to avoid leaving holes.
Measuring Tape: A flexible measuring tape is crucial for taking accurate body measurements and ensuring your tank top fits perfectly. Measure your bust, waist, and hips, and compare your measurements to the size chart of your chosen pattern. If you're drafting your own pattern, precise measurements are even more critical. Always measure yourself while wearing the type of undergarments you plan to wear with the tank top. Take measurements in a well-lit area and ask a friend to help you if needed. Record your measurements in a notebook or digital file for future sewing projects.
Seam Ripper: We all make mistakes, and a seam ripper is your best friend when it comes to undoing seams. This small tool has a sharp blade that easily cuts through thread without damaging the fabric. Keep a seam ripper handy while sewing, and don't hesitate to use it if you need to correct a mistake or adjust a seam. Practice using a seam ripper on scrap fabric to get a feel for how it works and avoid accidentally cutting the fabric. A good seam ripper will have a comfortable handle and a sharp, durable blade.
Thread: Choose a thread that matches your fabric color and is suitable for your fabric type. All-purpose polyester thread is a versatile option that works well for most fabrics. Cotton thread is a good choice for cotton fabrics, while rayon or silk thread can be used for more delicate materials. Ensure your thread is high-quality to prevent breakage while sewing. Test the thread on a scrap of fabric to check for color matching and stitch quality. Keep a variety of thread colors on hand to be prepared for different projects.
Tank Top Pattern (or an old tank top to trace): You can either use a commercial sewing pattern or create your own pattern by tracing an existing tank top that fits you well. Commercial patterns come in various sizes and styles, making it easy to find one that suits your preferences. If you're tracing an old tank top, choose one that is simple in design and fits you well. Lay the tank top flat on a large piece of paper and trace around it, adding seam allowances. Remember to add extra length if you prefer a longer tank top. If you're drafting your own pattern, you'll need to take accurate body measurements and use a pattern-making book or online resources to create the pattern pieces.
Fabric Marker or Tailor’s Chalk: These tools are used to transfer pattern markings onto your fabric. A fabric marker is a pen that is designed to write on fabric and is usually washable or fade-away. Tailor's chalk is a traditional tool that creates temporary markings on fabric. Choose a tool that contrasts with your fabric color for clear visibility. Test the marker or chalk on a scrap of fabric to ensure it doesn't leave permanent marks. Use these tools to mark seam lines, darts, and other pattern details onto your fabric accurately.
Iron and Ironing Board: Ironing is an essential step in sewing, as it helps to create crisp seams and a professional finish. Use an iron and ironing board to press your fabric before cutting, and to press seams open or to one side after sewing. Ironing also helps to set the stitches and prevent puckering. Always use the appropriate heat setting for your fabric type to avoid scorching or damaging the material. Keep a spray bottle of water nearby to dampen the fabric if needed. A well-pressed garment looks more polished and professional.

Step 1: Preparing Your Pattern and Fabric

Alright, let’s get the ball rolling! The first step in creating your DIY tank top is to prepare your pattern and fabric. This involves selecting the right pattern size, cutting out the pattern pieces, and prepping your fabric for cutting. Accurate preparation at this stage will ensure a well-fitting and professional-looking final product. Here’s a detailed breakdown of what you need to do:

Choose Your Pattern Size: If you're using a commercial sewing pattern, start by taking your body measurements (bust, waist, and hips) and comparing them to the pattern's size chart. It’s crucial to select the correct size to ensure a good fit. Remember, sizing can vary between pattern companies, so always refer to the specific size chart for the pattern you're using. If your measurements fall between sizes, it's generally best to choose the larger size, as it’s easier to take fabric in than to let it out. If you're using a traced pattern from an old tank top, ensure the original tank top fits you well. If needed, make adjustments to the traced pattern to achieve your desired fit. Consider the style of the tank top you want to create – a more fitted style may require a closer fit, while a looser style can allow for more flexibility in sizing. Always double-check your measurements and the pattern size chart before cutting your fabric.
Cut Out the Pattern Pieces: Once you've determined your size, carefully cut out the pattern pieces from the pattern sheet. Most commercial patterns are printed on large sheets of paper with multiple pattern pieces overlapping each other. Use sharp paper scissors or a rotary cutter to cut along the solid lines corresponding to your chosen size. Cutting accurately along the lines is essential for ensuring the correct shape and size of your tank top. If the pattern pieces are particularly intricate or have many curves, consider using pattern weights to hold the paper in place while you cut. Label each pattern piece clearly with its name and the pattern size to avoid confusion later on. If you're using a digital pattern, print it out at 100% scale and assemble the pieces according to the instructions.
Prepare Your Fabric: Before you start cutting, pre-wash your fabric to prevent shrinkage after sewing. Wash and dry the fabric according to the manufacturer's instructions. This step is especially important for natural fibers like cotton and linen, which tend to shrink more than synthetic fabrics. After washing and drying, iron your fabric to remove any wrinkles or creases. A smooth, flat fabric is much easier to cut and sew accurately. Fold your fabric in half, lengthwise, with the right sides together. This is the most common way to cut pattern pieces, as it allows you to cut two layers of fabric at once, creating mirror images for the front and back of your tank top. If your fabric has a directional print or nap, pay attention to the grain direction when folding and cutting. Lay the folded fabric on a large, flat surface, such as a cutting table or the floor.
Lay Out the Pattern Pieces: Arrange the pattern pieces on your fabric according to the pattern layout diagram provided in the instructions. This diagram shows the most efficient way to position the pattern pieces to minimize fabric waste. Pay attention to the grainline markings on the pattern pieces, which indicate the direction the pattern should be aligned with the fabric grain. The grainline should run parallel to the selvage edge of the fabric (the finished edge). Pin the pattern pieces to the fabric using straight pins, placing the pins perpendicular to the cutting lines and about 2-3 inches apart. Ensure the pattern pieces lie flat on the fabric without any wrinkles or folds. If you're using pattern weights instead of pins, place the weights on the pattern pieces to hold them in place. Double-check the placement of all pattern pieces before cutting to avoid mistakes.
Cut Out the Fabric Pieces: Using sharp fabric scissors or a rotary cutter, carefully cut along the edges of the pattern pieces. Cut through both layers of fabric if you folded the fabric in half. Use smooth, even strokes to create clean, accurate cuts. If you're using scissors, keep the bottom blade flat on the table and lift the top blade to cut. If you're using a rotary cutter, use a cutting mat underneath the fabric to protect your work surface. Cut just outside the cutting lines if you prefer to have a little extra fabric to work with, but be sure to maintain the shape of the pattern pieces. Once you've cut out all the fabric pieces, carefully remove the pins or pattern weights. Transfer any pattern markings, such as darts or notches, onto the fabric using a fabric marker or tailor's chalk. These markings are essential for aligning and sewing the pieces together accurately. Store the cut fabric pieces in a safe place until you're ready to start sewing.

Step 2: Sewing the Shoulder Seams

Now that we have our fabric pieces cut and prepped, it's time to start sewing! The first step in assembling our DIY tank top is to sew the shoulder seams. This will connect the front and back pieces at the shoulders, giving the tank top its basic shape. Sewing the shoulder seams correctly is crucial for the fit and structure of the garment. Let's walk through the process step-by-step.

Pin the Shoulder Seams: Take the front and back pieces of your tank top and place them right sides together. This means the sides of the fabric that will be visible on the outside of the finished garment should be facing each other. Align the shoulder edges, matching the raw edges and any notches or markings. Pin the shoulder seams together using straight pins, placing the pins perpendicular to the seam line and about every 2-3 inches. Make sure the fabric layers are smooth and even, with no puckers or folds. Pinning the fabric securely will prevent it from shifting while you sew, ensuring a straight and even seam. Double-check that you're pinning the correct shoulder seams – the front and back pieces should align smoothly at the shoulders.
Sew the Seams: Take your pinned fabric pieces to your sewing machine. Set your machine to a straight stitch with a stitch length of about 2.5mm. This stitch length is suitable for most lightweight to medium-weight fabrics. Position the fabric under the presser foot, aligning the raw edges with the seam allowance line on your sewing machine's needle plate. The seam allowance is the distance between the raw edge of the fabric and the stitch line. For most patterns, the seam allowance for shoulder seams is 1/2 inch or 5/8 inch. Lower the presser foot and begin sewing, backstitching at the beginning of the seam to secure the stitches. Sew along the pinned seam line, removing the pins as you go. Maintain a consistent seam allowance throughout the sewing process. Backstitch again at the end of the seam to prevent unraveling. Repeat this process for the other shoulder seam.
Press the Seams: After sewing the shoulder seams, it's important to press them to create a neat and professional finish. Pressing helps to set the stitches and flatten the seam, reducing bulk and preventing puckering. Place the sewn fabric pieces on your ironing board, with the wrong side facing up. Press the seams open, using the tip of your iron to gently open the seam allowance and flatten the fabric on either side of the stitching. If your fabric is delicate or prone to scorching, use a pressing cloth between the iron and the fabric. Pressing the seams open will distribute the bulk of the seam allowance, resulting in a flatter and smoother seam. Alternatively, you can press the seams to one side, either towards the front or the back of the tank top. If you choose to press the seams to one side, ensure you press them in the same direction for both shoulder seams. Pressing the seams is a crucial step for achieving a professional-looking garment.

Step 3: Attaching the Neckline and Armhole Binding

Okay, we're making great progress! Now, let's move on to attaching the neckline and armhole binding. This step is super important because it finishes the raw edges of the neckline and armholes, giving your tank top a clean and professional look. Plus, it adds a touch of style and comfort. There are several ways to bind the edges, but we'll focus on a simple and effective method using pre-made binding or self-fabric binding. Here’s how we'll tackle it:

Prepare the Binding: First, you'll need to prepare your binding. If you're using pre-made bias binding, you can skip the first part of this step. But if you're making your own binding from the same fabric as your tank top, start by cutting strips of fabric on the bias (at a 45-degree angle to the fabric grain). Bias strips have a slight stretch, which makes them perfect for curved edges like necklines and armholes. The width of your strips will depend on the desired width of your finished binding – typically, strips are cut twice the desired finished width plus seam allowances. For example, if you want a 1/2-inch finished binding and you're using a 1/4-inch seam allowance, you'll cut strips that are 1 1/2 inches wide (1/2 inch x 2 + 1/4 inch + 1/4 inch). Once you've cut your strips, join them together end-to-end to create a long strip of binding. Press the seams open to reduce bulk. If you're using pre-made bias binding, unfold one edge and press it to create a crease – this will make it easier to attach to your tank top.
Pin the Binding: With your binding ready, it's time to pin it to the neckline and armholes. Start by pinning the binding to the right side of the fabric, aligning the raw edge of the binding with the raw edge of the neckline or armhole. For pre-made bias binding, align the unfolded edge with the raw edge of the tank top. Overlap the ends of the binding by about an inch and pin them in place. For self-fabric binding, fold the binding in half lengthwise, wrong sides together, and press. Then, open it up and press each raw edge in to meet the center crease. Fold it in half again along the original crease and press. This creates a double-fold binding. Pin the binding to the neckline or armhole, aligning the raw edges. Use plenty of pins to hold the binding in place, especially around curves. Ensure the binding lies flat and doesn't stretch or distort the fabric. Distribute any fullness evenly around the curves.
Sew the Binding: Now, let's sew the binding to the neckline and armholes. Using your sewing machine, stitch along the crease closest to the raw edge of the binding, using a straight stitch and the appropriate seam allowance (usually 1/4 inch or 3/8 inch). Sew slowly and carefully, especially around curves. Keep the fabric and binding aligned as you sew, and remove the pins as you go. When you reach the overlap, trim the excess binding, leaving about 1/2 inch overlap. Fold the end of one piece of binding over the other and sew through all layers to secure. After sewing, trim the seam allowance to reduce bulk, especially around curves. Clip into the seam allowance at regular intervals along the curves to allow the binding to lie flat.
Flip and Press: Next, flip the binding to the wrong side of the tank top. Fold the binding over the raw edge of the fabric, encasing it completely. Press the binding in place with an iron, creating a crisp edge. If you're using pre-made bias binding, the folded edge should cover the stitching line on the right side of the fabric. If you're using self-fabric binding, the double-fold will create a neat, finished edge. Pin the binding in place on the wrong side of the fabric, ensuring it covers the stitching line and lies flat. For a professional finish, consider mitering the corners of the binding at the underarms. This involves folding the binding diagonally at the corner to create a clean, pointed finish.
Topstitch the Binding: Finally, it's time to topstitch the binding in place. Topstitching is a line of stitching that is visible on the right side of the fabric, and it helps to secure the binding and add a decorative touch. Using your sewing machine, stitch close to the edge of the binding on the right side of the fabric. Use a straight stitch and a slightly longer stitch length (around 3.0mm) for topstitching. Sew slowly and carefully, keeping your stitching line even and consistent. Ensure you catch the binding on the wrong side of the fabric as you sew. If you prefer, you can also hand-stitch the binding in place using a blind stitch for an invisible finish. Once you've topstitched the binding, give it a final press with the iron to set the stitches and create a professional finish. Inspect the binding for any loose threads or imperfections and trim them if necessary.

Step 4: Sewing the Side Seams

Alright, let's keep the momentum going! We're now at the step where we sew the side seams of our DIY tank top. This is where the front and back pieces come together to form the body of the tank top. Getting the side seams right is crucial for the fit and shape of your garment. We'll go through this carefully, ensuring a smooth and professional finish.

Pin the Side Seams: Begin by laying your tank top flat, with the right sides of the fabric facing each other. This means the outer fabric of both the front and back pieces should be touching. Align the side edges of the front and back pieces, matching the raw edges and any notches or markings. Start pinning from the bottom edge of the tank top, working your way up to the armhole. Use straight pins to secure the fabric, placing them perpendicular to the seam line and about every 2-3 inches. Make sure the binding at the armholes matches up neatly and is pinned securely. Ensure the fabric layers are smooth and even, with no puckers or folds. Pinning the fabric carefully will prevent it from shifting while you sew, ensuring a straight and even seam. Double-check that the side seams align properly before you start sewing.
Sew the Seams: Take your pinned fabric pieces to your sewing machine. Set your machine to a straight stitch with a stitch length of about 2.5mm. This stitch length is suitable for most lightweight to medium-weight fabrics. Position the fabric under the presser foot, aligning the raw edges with the seam allowance line on your sewing machine's needle plate. The seam allowance for side seams is typically 1/2 inch or 5/8 inch, but refer to your pattern instructions for the exact measurement. Lower the presser foot and begin sewing, backstitching at the beginning of the seam to secure the stitches. Sew along the pinned seam line, removing the pins as you go. Maintain a consistent seam allowance throughout the sewing process. Backstitch again at the end of the seam to prevent unraveling. Repeat this process for the other side seam.
Press the Seams: After sewing the side seams, it's important to press them to create a neat and professional finish. Pressing helps to set the stitches and flatten the seam, reducing bulk and preventing puckering. Place the sewn fabric pieces on your ironing board, with the wrong side facing up. Press the seams open, using the tip of your iron to gently open the seam allowance and flatten the fabric on either side of the stitching. If your fabric is delicate or prone to scorching, use a pressing cloth between the iron and the fabric. Pressing the seams open will distribute the bulk of the seam allowance, resulting in a flatter and smoother seam. Alternatively, you can press the seams to one side, either towards the front or the back of the tank top. If you choose to press the seams to one side, ensure you press them in the same direction for both side seams. Pressing the seams is a crucial step for achieving a professional-looking garment.

Step 5: Hemming the Bottom Edge

We're almost there, guys! The final step in completing our DIY tank top is hemming the bottom edge. Hemming not only gives your tank top a clean and polished look, but it also prevents the fabric from fraying. There are several hemming techniques you can use, but we'll focus on a simple and effective method that works well for most fabrics: the double-fold hem. Let's get to it!

Prepare the Hem: Before you start hemming, you'll need to prepare the bottom edge of your tank top. First, turn up the raw edge of the fabric by 1/4 inch to the wrong side and press it with an iron. This creates a small fold that will be hidden inside the hem. Pressing the fold helps to create a crisp, even edge and makes it easier to sew the hem. Next, turn up the folded edge another 1/4 inch (or the desired hem depth, if you prefer a wider hem) to the wrong side and press again. This creates the double-fold hem, which encases the raw edge of the fabric and prevents fraying. The double-fold hem is a durable and professional-looking finish that is suitable for most lightweight to medium-weight fabrics. Use plenty of steam while pressing to help the fabric hold its shape.
Pin the Hem: With the hem prepared, it's time to pin it in place. Use straight pins to secure the folded hem, placing the pins perpendicular to the folded edge and about every 2-3 inches. Make sure the folded edge of the hem is smooth and even, with no puckers or folds. Pinning the hem securely will prevent it from shifting while you sew, ensuring a straight and even hemline. If you're working with a curved hem, you may need to use more pins to hold the fabric in place. For slippery fabrics, consider using fine pins or silk pins to avoid snagging the material. Double-check that the hem is the same width all the way around before you start sewing.
Sew the Hem: Now, let's sew the hem. Take your pinned fabric to your sewing machine. Set your machine to a straight stitch with a stitch length of about 2.5mm. This stitch length is suitable for most fabrics. Position the fabric under the presser foot, aligning the folded edge of the hem with the edge of the presser foot or the hemmer foot, if you're using one. Lower the presser foot and begin sewing, backstitching at the beginning of the seam to secure the stitches. Sew along the folded edge of the hem, removing the pins as you go. Maintain a consistent distance from the folded edge to create an even hemline. If you're using a hemmer foot, it will automatically fold the fabric as you sew, creating a neat and professional hem. Sew slowly and carefully, especially around curves. Backstitch again at the end of the seam to prevent unraveling.
