Learn How to Attach Blanket Binding Step by Step

Understanding Blanket Binding and Why It Matters

Blanket binding is the fabric trim that finishes the edges of a blanket, providing both functional and decorative benefits. This binding serves several practical purposes: it prevents fraying of the blanket's edges, reinforces the seams to extend the blanket's lifespan, and creates a polished, professional appearance. Whether you're working with fleece, cotton, quilted fabric, or minky material, adding binding transforms a raw-edged blanket into a finished product that looks store-bought and feels durable.

The binding itself is typically made from bias tape—fabric cut on the diagonal grain of the material. This diagonal cutting allows the binding to stretch slightly and conform to curves without puckering. You can purchase pre-made bias tape in hundreds of colors and patterns at fabric stores, or you can create your own binding from coordinating fabric. Pre-made binding comes in various widths, most commonly half-inch and one-inch finished widths, which refers to how wide the binding appears on the final blanket.

Understanding the difference between single-fold and double-fold binding is important before you start. Single-fold binding has edges that are folded inward once, while double-fold binding is folded twice, creating a more durable edge. Double-fold binding is generally recommended for blankets because it withstands frequent washing and wear better than single-fold options. The extra layer provides reinforcement and a more finished look.

Blanket binding works on blankets of any size, from small receiving blankets to king-sized bed blankets. The technique remains consistent regardless of scale. Learning this skill opens possibilities for creating gifts, refreshing old blankets, or finishing quilting projects. Many people find attaching binding satisfying because the results are immediately visible and create a noticeable improvement in the blanket's appearance and longevity.

Takeaway: Blanket binding serves practical purposes—preventing fraying and reinforcing edges—while also improving the blanket's appearance. Double-fold bias tape is the most durable choice for blankets that will be washed regularly.

Gathering Your Materials and Tools

Before beginning your binding project, assembling the right materials ensures smooth progress and professional results. The primary material you'll need is bias tape binding. Measure your blanket's perimeter by adding the length of all four sides. For a standard 40-by-60-inch blanket, this totals 200 inches, so you'd need approximately 200 to 220 inches of bias tape to account for seam allowances and corner overlap. Purchase slightly more than your calculated amount—extra binding is useful for practice or correcting mistakes.

You'll need coordinating thread that matches either your blanket or your binding, depending on your preference. Many sewers choose thread that matches the binding since this makes seams less visible. Select thread designed for your fabric type; cotton thread works well for most blanket fabrics, though polyester thread adds durability for items that receive heavy use. Have several bobbins wound with your chosen thread before starting, as you'll need consistent thread throughout the project.

Essential tools include a sewing machine in good working order, with a needle appropriate for your fabric weight. For most blankets, a standard 80/12 needle works well, though thicker fabrics like minky or fleece may require a 90/14 needle. A walking foot attachment significantly improves binding attachment by feeding the binding and blanket layers evenly, preventing the top layer from shifting. If your sewing machine didn't come with a walking foot, many are available as affordable aftermarket purchases.

Additional helpful tools include fabric scissors or a rotary cutter for trimming, pins or clips to hold binding in place, a measuring tape, an iron for pressing binding open and finished seams, an ironing board, and a seam ripper for correcting mistakes. A quarter-inch presser foot or binding foot—specialized feet designed for attaching binding—can improve accuracy, though not strictly necessary if you're experienced with maintaining consistent seam allowances.

Takeaway: Calculate your blanket's perimeter, purchase slightly more binding than needed, gather matching thread, ensure your sewing machine is in good condition with appropriate needles, and consider investing in a walking foot and binding foot to improve results.

Preparing Your Blanket and Binding for Attachment

Proper preparation prevents problems during binding attachment. Start by trimming your blanket's edges to ensure they're straight and even. Many blankets have slightly uneven edges from the cutting process. Use a rotary cutter and ruler or mark straight lines with fabric pencil and cut with scissors. Square corners are important because binding attaches more smoothly to straight edges. If your blanket has rounded corners, measure from the corner inward about two inches along each side, mark an arc between these points, and cut along the curve for a professional rounded corner that's easier to bind.

Press your blanket thoroughly with an iron on a setting appropriate for your fabric. This removes wrinkles and creases that can shift during binding attachment. Pay special attention to the edges, pressing them flat so binding sits smoothly. If your blanket is quilted or has multiple layers, ensure all layers are smoothly pressed together and no batting has shifted.

Prepare your binding by opening it fully and pressing it flat if it was folded tightly in packaging. Some binding comes slightly wrinkled, and pressing eliminates these wrinkles so it lies flat and attaches evenly. If you're using a particularly stubborn binding, lightly misting it with water before pressing helps relax the creases. Allow the binding to cool before handling to set the press.

If using pre-made binding that isn't pre-folded, fold it in half lengthwise with wrong sides together and press. The binding should now have a fold on one long edge and raw edges on the other long edge. Prepare binding seams by connecting individual pieces end-to-end if your binding comes in shorter lengths. Sew two pieces together at a 45-degree angle, trim the excess fabric, and press the seam flat. This creates a continuous length of binding that flows smoothly around your blanket without obvious seam breaks.

Takeaway: Trim your blanket's edges straight, press the blanket and binding thoroughly, and connect binding pieces at 45-degree angles if necessary, creating a continuous binding length ready for attachment.

Attaching Binding to Your Blanket: The Step-by-Step Process

Begin by finding the midpoint of each blanket side and the midpoint of your binding. Mark these points lightly with a fabric pencil or pin. Starting at the midpoint of one side (rather than a corner) helps distribute any bunching evenly. Unfolding one long edge of your binding, place the raw edge of the binding against the raw edge of the blanket, with binding and blanket right sides together. Pin or clip binding to the blanket every few inches, keeping edges aligned precisely.

Set your sewing machine to a 2.5 stitch length—slightly longer than standard seaming—and attach thread in your prepared bobbin. Begin sewing about six inches before your starting point, using a quarter-inch seam allowance (the standard for binding attachment). Sew slowly and steadily, keeping the binding edge aligned with the blanket edge. Stop and check alignment frequently, especially during your first project. Sew until you reach a corner, stopping exactly one quarter-inch before the corner point.

At corners, executing a proper turn ensures neat binding appearance. Stop one quarter-inch before the corner, backstitch, and remove your blanket from the machine. Fold the binding upward at a 45-degree angle, creating a diagonal fold at the corner. Then fold the binding back down so it aligns with the next blanket side. The fold creates a small triangle at the corner. Pin this fold in place, then sew along the next side's edge, starting exactly at the blanket corner point. Continue this corner process for all four corners.

When you near your starting point, overlap the binding by about two inches. Trim the binding ends at 45-degree angles and overlap them, sewing through all layers to create a continuous binding loop. This angled overlap creates a less visible seam than a straight overlap. Press your stitched binding to set the seam, then fold the binding to the back of the blanket, wrapping it around the edge so the folded edge of the binding covers your stitching line. Pin in place and topstitch from the front of the blanket, using thread that matches your blan
