I use to use leftover poly blends from clothes making in quilt, many years ago. The poly blends will out last 100% cotton. Polyester batting will outlast other kinds of batting also. My Son has a quilt I made 40 years ago using both and a few pieces of cotton. The polyester batting looks the same as when it was new. The cotton squares are totally gone.
I have a rubber maid container of poly blend fabrics and I am eager to make quilts with it.
The only problem I have is I'm not going to live long enough to sew up all the fabrics I have.
Never heard of anyone living to be 200 - 250 years old.
