The above quilt is 100% polyester - no batting - polyester back. (Gees bend copy)
The above quilt is 100% poly - with light cotton batting and poly back.
I made all of those quilts from that 30 box stash I bought on Craigs list. I like working with poly in projects that can be applique or not many small seams - when there are lots of seams old style polys are too thick to really do intense work with.
I also have been using the huge pieces of polyester as batting in quilts - it works wonders! Its heavy warm and has a nice drape -- ! Try it!
