I'm afraid I can't help with the fabric, as I don't know. However, if it's any consolation, I remember Carol Doak telling us in a quilt workshop at my guild that fabric has a shelf life, so you need to buy it when you see it. I know that I've read in magazines where they give you the name of the fabric used, that they cannot guarantee that the fabric will still be in stock when the magazine comes out. However, some of the QB "help line" have offered some beautiful alternatives. Good luck.
