I've taken 3 of the classes on Craftsy. I LOVE them! Once you buy the class, you get to keep it forever, you can interact with others who are doing the same class, you can ask questions and get answers, pause, rewind and go over any spot again if you need to, write notes to yourself,and add bookmarks to sections that are important to you, and re-do the class any time you want, as many times as you want. Can't get better than that. Well worth the money, and sometimes you can get them on sale. What's not to like???
