Making Bias

How to Make Bias Binding

Bias binding encloses fabric edges for a neat, often decorative finish. Because of the bias direction, the binding wraps around curves without puckering. You can make either a single-fold or double-fold binding.

  1. Fold the fabric diagonally so that one selvage is at a right angle to the other selvage. Press along the fold – the direction of the fabric grain at the fold is the bias grain, Cut along the pressed line. Set aside the triangle of fabric.
  2. Multiply the desired finished width of the binding by four to determine how wide to cut the strips. For example, for 1/4″ (6mm) finished binding, you’ll need strips 1″ (2.5cm) wide. Beginning at the diagonal cut edge of the fabric, measure and mark parallel lines that are the desired cutting width. After you have drawn the last strip, discard the triangular remnant – or save it as a scrap.
  3. Fold the fabric right sides together, matching selvages to form a tube. Match the marked lines so that one strip of fabric extends beyond the tube on each side. Sew a 1/4″ (6mm) seam and press it open. Starting at one end, work around the tube to cut one continuous strip along the marked line.
  4. Press both long edges to the center of the tape, taking care not to distort the width of the strip. Press the strip in half again to create the double fold.
