I'm in the process of doing both of the Quilting Quickly courses at Craftsy. They are wonderful! Some of the best quilting-related money that I've spent. She really goes into a lot of depth about everything, so it's much more than a quick You Tube tutorial. I think the cost is more than reasonable. Plus, I just enjoy watching them on the computer, especially when there's nothing to watch on TV (grin).
Be sure to wait until you get a 50% offer to sign up....no need to pay full price because they send out the 50% off notices quite frequently. Just sign up for the Craftsy mailing list. If you're on any of the larger mailing lists, such as Fons & Porter or McCalls, you should get the offers through them also.
