Start with a rectangular, square, or long narrow piece of cloth.
Fold one corner, C, to get 5 true bias B E..
Cut through the fold, B E. Make a parallelogram by joining straight edges (those of equal length) BC and AD with the seam on the wrong side of the material. Stitch and press seam open.
On the wrong side of the material, draw pencil lines the width desired for the bias -1¼" or 1½" Begin at one bias edge, as at the left, and mark across toward the bias edge on the right.
Seem straight edges together, making a tube of the cloth.
With the material wrong side up, grasp the lower left and upper right-hand corner. Turn over and bring together the straight edges, with one corner of the cloth the width of the Bias (1¼ or 1½”) beyond the other. Pencil lines will meef, except at corners. Stitch and press the seam apart.
Cut along the penciled marks and you will have a continuous bias.
Place cord inside a fold of bias. Stitch, using a long machine stitch and a cording foot.
One yard of 35“ material will cut about 20 Yards of bias 1½ wide.
One-quarter yard of 40" material will cut about 10 yards of bias 1¼" wide
