I have and I like the way it turned out. I just used leftover strips from other projects. I don't have a picture of the quilt, because I made it as a gift for a friend and it is with her. The pictures here are of a wall hanging I made form the blocks that were leftover from the Hidden Wells quilt I made for my friend.
This is a really fun technique and I did use the tutorial from moosestashquilting.blogspot. Joan's tutorial is really good.
