I had the pleasure of taking a class with Leah Day last spring and she is terrific... she takes such a laid back approach to FMQ. She had us come to class with a dozen 10-12 inch sandwich blocks made up of solid fabric colors (so we could see our stitches) and we practiced different FMQ patterns in each block. From time to time I still practice using the same block ideas just to keep my skills up. Angela Walters is also a good instructor and she too, has a Craftsy class.
