Bias tape is a versatile sewing notion used to finish raw edges, bind seams, and add decorative touches to various sewing projects. Made from fabric cut on the bias (diagonally across the grain), bias tape has natural stretch and flexibility, making it ideal for curves and irregular edges. Whether you’re a beginner or an experienced sewist, learning how to sew bias tape properly can greatly enhance your projects.
Types of Bias Tape
There are several types of bias tape, each serving a different purpose:
Single-Fold Bias Tape – This is a strip of fabric folded once on each side toward the center. It is commonly used for decorative edges, facings, and casings.
Double-Fold Bias Tape – This type has been folded again in half, making it thicker. It is often used for binding seams and finishing raw edges.
Wide Bias Tape – Used for larger projects where more coverage is needed, such as quilts and home décor items.
Stretch Bias Tape – Typically made from knit fabric, it works well on stretch fabrics like jerseys.
How to Make Bias Tape
You can buy pre-made bias tape or make your own for a perfect match to your project. Here’s how:
Cut Fabric on the Bias – Place your fabric on a flat surface and cut strips at a 45-degree angle to the grainline.
Join Strips (if Needed) – If you need a longer piece, place two strips at right angles, stitch diagonally, and trim the seam allowance.
Press the Seams – Open the seam and press flat.
Fold and Press – Use a bias tape maker or manually fold and press the edges toward the center. If making double-fold tape, fold again down the middle and press.
How to Sew Bias Tape
1. Enclosing an Edge (Binding)
This method is great for finishing edges on quilts, aprons, or necklines.
Sandwich the raw edge between the folds of double-fold bias tape.
Pin or clip it in place.
Stitch close to the edge, ensuring you catch both sides of the tape.
2. Facing an Edge (Single-Fold Tape)
This method is ideal for armholes or necklines.
Open one side of the bias tape and align it with the raw edge of the fabric, right sides together.
Stitch along the crease, then fold the tape over the edge and stitch again.
3. Mitering Corners
For a neat finish on square edges:
Stop stitching ¼ inch from the corner, fold the tape at a 45-degree angle, then continue stitching along the next edge.
