I'm self-taught FMQ but if I took a class, my main question would be --
how do I handle a large quilt?
Quilting on small squares is easy to learn. It's the slippage while dealing with a large quilt is my problem. Plus, with arthritis and fibromyalgia, it's almost impossible to do.
So, I've had to switch to QAYG techniques in order to do large quilts.
Hope this helps.
