I really liked Machine Quilting by Wendy Butler Burns. She gives great information on sandwiching, quilting, and all the way to binding. I took her class when I was starting quilting again after a 20 year hiatus.
I love Craftsy. Over the last year and a half I have signed up for over 20 quilting classes. Twice I signed up for classes that I felt like were not for me. True to their word, Craftsy refunded my money - no questions asked. Once you purchase a class, you will get an email with a link to get the next one for $25. That is the most I will pay for one and I find them on sale a lot.
Enjoy!!!
