I've bought both of Jenny's courses and the one on free-motion quilting. I've learned a lot from all! The "trick" is finding a link that takes you to the lower-price. (Mine came in e-mails from other groups.)
I was sad to learn that Jenny is NOT going to do the third course for Craftsy. She is going to offer all her expertise through YouTube. Nice to get them for free, but I really like the Craftsy format which is a much longer and more detailed video than the YouTube ones.
