How to Bind with Bias Tape:
If possible, start the binding in an inconspicuous place. Pin in place for stitching. Always baste on curves or angles.  On bulky fabrics, leave about 2 inches of the bias strip unstitched at the starting point. Stitch around the garment, and stop slightly before reaching the starting point: cut bias strip, leaving about 2 inches. Fold the garment so that the ends of strips can cross each other at right angles. Stitch strips together on grain close to the garment. Press seam open and trim. Finish stitching binding to garment.For lightweight fabrics simply lap the ends. Fold 1/2 inch of strip to the wrong side, on the straight grain and stitch. working side on the straight grain and stitch. As you near the end of this stitching line, lap the second and over the folded end, and cut the excess bias on straight grain. Finish stitching to garment.


A Handy Tool for Making Bias Tape:
Clover produces a handy bias tape tool that makes bias strips in even widths. Here is the information from their packaging:
  • Pass the diagonally cut fabric through the tape maker. If it does not pass easily, cut the starting end to a point and force it through using an awl in the center groove.
  • Pass the diagonally cut fabric through the tape maker. If it does not pass easily, cut the starting end to a point and force it through using an awl in the center groove.
  • Wind and pin the finished tape for easy use.
  • Danger! Do not contact the iron to the tape maker. The metal portion which is heated up may cause you a burn.

How to Make Your Own Custom Bias Tape in Using Any Fabric:
  • Prepare a rectangle of your fabric on the straight grain. On the wrong side, mark a true bias line (line 1.) from the upper corner to the opposite side.
  • Measure the width of the bias from this line and draw a second line parallel to the first. Continue to measure and mark until you have sufficient length.
  • With right sides together, form a tube by folding rectangle so that the lines on the lengthwise edges match. Line 1 should extend above the other lines a shown.
  • Pin edges and stitch, making a 1/4 inch seam. Press seam open. Start to cut on line 1 and continue to cut around the tube on the marked lines.
How to Estimate Bias Yield:
This chart will help you to estimate how many individual bias strips can be cut from 1 yd. of fabric. Five handy cutting widths for bias strips are given.

The cutting widths include 1/2" for turning under each raw edge 1/4" and an additional 1/4" for removing the slack:

  • Strips cut 11/4"wide can be used for 1/4" double-fold bias binding or 1/2" single-fold bias tape.
  • Strips cut 13/4"  wide can be used for 1/2" double-fold bias binding or 1" single-fold bias tape.
  • Strips cut 21/4"  wide will cover 1/4" cable cord for welting or make 3/4" double fold bias binding.
  • Strips cut 23/4"  wide can be used for 1" double-fold bias binding or 2" single-fold bias tape.
  • Strips cut 33/4"  wide can be used to cover 3/4" cord for welting.

1 yd. of fabric yields approximately this amout of bias strips (pieced separately).

How to Estimate Bias Yield (METRIC)

The cutting widths include 13mm for turning under each raw edge 6mm and an additional 6mm for removing the slack:

  • Strips cut 3.2cm wide can be used for 6mm double-fold bias binding or 13mm single-fold bias tape.
  • Strips cut 4.5cm  wide can be used for 13mm double-fold bias binding or 2.5cm single-fold bias tape.
  • Strips cut 5.7cm  wide will cover 6mm cable cord for welting or make 20mm double fold bias binding.
  • Strips cut 7cm  wide can be used for 2.5cm double-fold bias binding or 5cm single-fold bias tape.
  • Strips cut 9.5cm  wide can be used to cover 20mm cord for welting.

0.95m of fabric yields approximately this amout of bias strips (pieced separately).
