I watched the class and it is well done. Most of us probably already create interesting backs, but she teaches the logic behind it and shows you how to work out the math. The last thing she does is build a back with leftover fabric, making a scrappy mosaic of colors. She shows you how to creatively arrange it, break it down into sections, and sew it all together. If you don't already have the confidence to make a creative back, you will when you're done watching this class.
