I used 505 basting spray for the first time today. The quilt sandwiched together pretty good, (couple bad wrinkles in the backing), and seems to be tightly stuck together; however, I am having a terrible time moving the fabric around for FMQ. I started FMQ pretty quickly after spraying and now wonder if I needed to let it dry longer? I'm not good at FMQ, but I've never had trouble sliding the fabric around.
