One WalMart close to me carries the Quilt of the Month fabric. I like the way it feels and looks. I buy a lot of that.
If I'm making a quilt that I know will be used and washed a lot, I use a cotton/poly (higher % of cotton) fabric. It will hold up to lots of abuse and be soft as cotton. I think the cotton/poly blend fabric will soon be big. The fabric industry can sway consumers any way they decide too. Several well known spokespersons say I use this and love it, it's all it takes.
