2. Cut a square piece of fabric. I made mine 25 cm x 25 cm (10″ x 10″) but you can make it as big or small as you want. With this size, I was able to make a 2,4 m strip of bias (2 1/4 yards).
lines every 2,5 cm (1″) starting at the top (along the bias) on the wrong side of the fabric. The last line might be slighty smaller (mine’s 2,2 cm), that’s because my seam allowances were a little bit too deep.
7. That’s the tricky part, at least for me. With right sides together, bring the edges together and match the lines along the seam line. The first row of each side should be offset, like on the picture. Pin together and stitch very close to the edge.
8. After the tricky part, the fun one! Now that you have a tube, start cutting the first offset row following the continuous line until the end.
9. Now you have the strip of fabric cut on the bias and you need your cord.
10. Place the cord on the wrong side on the bias, fold the bias in half to sandwich the cord and secure it in place with pins.
11. With a zipper foot, stitch as close as possible to the cord (possibly with a matching thread! I’m using a constrating one so you see it better).
