I was in Joann's just a couple of days ago and they had co-mingled their "quilt fabric" in with their calicos at $9/yd. But their description of "quilt fabrics" was not what we would call quilt fabrics at the LQS. Also the store is such a mess.
I use fannel for the backs cause they are cuddly. As I tell those who get a quilt, if they complain, they will never get another and if they put it "away to save it" they will never get another. Mine are made to be used and abused with smiles.
