If you need fabric to practice on, and I did, head for the nearest Goodwill Store, or any second-hand store like that. I came out with bundles of shirts, sheets, table linens, and the like, all for $20. It's probably stuff people would turn into rags, but I'm using it to make practice sandwiches, and it cost so little, that I don't mind just throwing them away when I'm done. This find was so terrific for a Newbie like me who has never done FMQ before, needs lots of practice, and is a quilter on a fabric budget. I am getting the piecing OK because I've always done sewing, but the FMQ is the Green Monster I still have to tame! But I'm getting better all the time. So if you need cheap, disposable fabric for your FMQ sandwiches, here's a tip on where to find it.
