I have done hours of practicing on 12"sandwiches with leftover fabric and scraps of batting. I am having a difficult time transitioning from small pieces of practice to a quilt-can't seem to figure out how to move the quilt around easily on my DSM. Would it be of benefit to practice FMQ'ing on old sheets with an old mattress pad or something as the sandwich? Or purchasing a "quilt" from Goodwill or thrift store and just quilt over whatever is there? Or would this not be close enough to replicate the actual quilting technique? I am stuck and I soooooo want to figure this out!
