Chick 30116, thats a pretty neat story and good advice! I have cut up many pairs of jeans I've collected and have more still to cut. I will be making squares to do a rag quilt so this thread is interesting to me as I have not ever made one yet.
My method albeit good or bad, was to cut along the outer flat feld seams from hem to waist; cut the inside leg seam the same and save those as I saw them used for shoulder straps on a denim handbag! That might come later, lol. I removed the zippers to save, the pockets to save and then I will cut the remaining fabric into squares in whatever sizes I can get out of the fabric. Then I plan to square up as many as possible into "same size" squares. I will then embroidery on some of the squares. Hope that makes sense. I was thinking of using flannel for the back and not sure if any batting.... maybe none?
