I ordered a Kaffe Fassett backing fabric online and was disappointed that it was thin (especially for the price), but then realized that I had not read the description closely. It is sateen. It glided smoothly through the machine, which is a plus for backing, but I would have preferred a heavier cotton. I used it on the back of a quilt I made for my daughter's guest room. The colors were perfect for that quilt, and it will rarely need washing. So I don't know how it will hold up. I'm not usually into such wild colors and prints so don't have a lot of experience with his fabrics. Just mentioning this so that others will read the description more carefully than I did.
Now today I have tried to look up the same backing fabric and find that some sellers do not mention that it is sateen. It may have changed or there may be different versions of the fabric with that same print. I don't think his quilt fabrics are sateen, other than these wide backs.
