I have many craftsy classes on my computer. They will be there forever to look at! But, wait until they are half price. If you sign up for one and realize you made a mistake, they are great about refunds. I needed to do some major alterations for my daughter and figured I could use a refresher course on alterations. I was absolutely amazed with all the new tricks I learned from the course. Saved me a tremendous amount of work and my daughter a huge amount on a new wardrobe!
