I LOVED the Pictorial Quilting Class, but Stupendous Stitching has been my favorite so far. I signed up for Stitch and Slash, and got the Sewing with Texture free by demoing a Bernina machine recently.

I've also done Jeanius and the Jacket class, but I find the garment classes to not be as good as the quilting classes, maybe because they are harder... The jacket pattern doesn't fit me well, but the class doesn't cover alterations :(

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.
