I bought both the "Quilting large quilts on a small machine" and "Beyond basic machine quilting". Both were taught by Ann Peterson and both were excellent. I couldn't pick a favorite, I learned SOOOO much from both. But the BEST thing about Craftsy classes is that once you buy the class, it's yours FOREVER. You can make notes, ask questions, post pictures and interact with others taking the class, and go back to the class anytime you want to. I'll definitely buy more Craftsy classes in the future.
