I, too, liked Ann Peterson's Quilting Big Projects on a Small Machine. I also like Leah Day's classes on Free Motion Quilting. I buy the Craftsy classes when they are on sale and I consider them well worth money. I have never had a question for the instructor as the instructions were clear; but the times I have sent a message to the instructor, I got a fast response. I like the fact that I can work at my own speed, view the lessons at any time, and look back over lessons as often as I like.
