Craftsy has a new class that's on sale right now for $14.99 by Debbie Caffrey: 'Cut to it: strategies for smarter quilting'. It's a great class that addresses among other things, this very issue ~ not w product but w a couple of unique and well-explained hand positions.
I'm a lifelong quilter/sewist and learned ALOT from this class. It's one I highly recommend to everyone.
