At the risk of being accused of being a quilt snob, I would like to go on record and say that I don't like polyester and would never knowingly put it in a quilt. Poly doesn't have the draping quality that cotton has and batting beards through it like crazy. It also doesn't press well and smells awful when you press it. If I'm going to take the time to make a quilt from scratch, I want to use good quality cotton. Cotton has endured the test of time. Who wants to use a fabric that melts!!! There I've said it....now I'm getting outta here quicK!!!!
