Twenty five years ago when 100% cotton fabric was not as easy to come by as cotton/poly blends, I made my son a bed quilt using scraps of what I had. He slept under it for 8 or 9 years and took it to college with him. At the end of 4 years of college he brought the quilt back to me to "fix". Just about every place where there had been a cotton/poly blend fabric was a hole. That fabric completely wore out....the cotton was still in place and holding together. I had to make a replica of the quilt for my son and learned a very valuable lesson....my stash was cleaned immediately of all cotton/poly fabric....and I have never used it for another quilt....it just doesn't have the staying power!
