I have signed up for several quilt related classes on Craftsy, and I love them. The first I signed up for was $19.99 and the others were $19.99 with a buy one get one free special during December. I think if you join their web site they will begin to send you information when they run specials. I find the videos well done and I love that I can add my own personal notes (or bookmarks) any time I like during a video. It helps me find a technique I would like to remember.
The Sew-Cal-Gal blog is running a FMQ challenge this year, with an emphasis on improving FMQ. It is not an 'online' class but tutorials. It could be helpful though. Here is the link
