They have a demo right under the pictures on the top left hand side. It might help you see if you'd really like it or not. The only use I personally see is for the shapes that are odd (like a butterfly) that you can applique with. It's easier just to cut long strips for the regular sized strips, squares and triangles. Happy Shopping!
