After watching the Quilting Arts Video "Gathering of Leaves" by Heidi Lund whose work I love, I decided to do some of my own. They are sewn on Dupioni silk with light green on the underside. Not hard to do. I like to have pieces around so that if I need something, I have a starting point. It's a good way to feel productive when you can't concentrate because of the confusion caused by upgrading some of the things in the house.
