Bias Tape: Single vs. Double Fold
Whether you're a seasoned sewist or just starting your sewing journey, understanding the ins and outs of bias tape can elevate your projects. Bias tape, often simply referred to as "bias binding," is a versatile and essential component in the sewing world. It’s used to bind edges, create a clean finish, add decorative elements, and more. In this blog post, we'll explore what bias tape is, the difference between single fold and double fold bias tape, and how to use each type effectively.
What is Bias Tape?
Bias tape is a strip of fabric cut on the bias, meaning it’s cut diagonally across the grain of the fabric. This diagonal cut gives the tape a slight stretch, making it easier to conform to curves and irregular shapes. Bias tape is typically used to finish raw edges on garments, quilts, and home decor items.
Single Fold vs. Double Fold Bias Tape
Understanding the difference between single fold and double fold bias tape is crucial for choosing the right one for your project.
Single Fold Bias Tape
Single fold bias tape is a strip of fabric folded once along each long edge. The folds are typically pressed to meet in the center, creating a narrow tape that can be unfolded for sewing.
Structure: It has two folds, one on each long edge, making it flat and wide when fully opened.
Uses: Single fold bias tape is often used for narrow hems, facing armholes and necklines, and as a decorative trim.
Application: To apply, you unfold the tape, align it with the fabric edge, sew along the fold line, then fold the tape over the raw edge and stitch it in place.

Double fold bias tape starts as a single fold bias tape but is folded in half again along the center, encasing the raw edges completely.
Structure: It has three folds – two along the edges and one down the middle, making it thicker and more durable.
Uses: Double fold bias tape is perfect for binding quilts, finishing the edges of garments, and adding strength to seams.
Application: To apply, you simply encase the raw edge of your fabric within the tape and sew it in place, typically with a single line of stitching.
How to Make Your Own Bias Tape
While pre-made bias tape is readily available in fabric stores, making your own allows for custom colors and patterns that perfectly match your project.
Cutting: Cut your fabric on the bias (at a 45-degree angle to the grain) into strips of your desired width. For single fold bias tape, cut strips twice as wide as the final tape width. For double fold bias tape, cut strips four times as wide.
Folding: Use a bias tape maker or fold the edges manually. For single fold, press the edges to meet in the center. For double fold, first create single fold tape, then fold it in half and press again.
Joining Strips: If your project requires a long length of bias tape, join strips by placing them at right angles to each other, sewing diagonally, and trimming the excess fabric.
Tips for Using Bias Tape
Pressing: Always press your bias tape well before and after sewing to ensure crisp edges and a professional finish.
Pinning/Clipping: Use pins or fabric clips to hold the tape in place before sewing, especially on curves.
Stitching: For a clean look, use a matching thread and stitch as close to the edge of the tape as possible.
Shop bias tape
Bias tape, whether single fold or double fold, is a valuable tool in your sewing kit. Understanding the differences and applications of each type ensures that your projects not only look great but also stand the test of time. By mastering the use of bias tape, you can add a professional touch to your creations, making them uniquely yours.
Happy sewing!
