After I laid it out on the design wall I thought "ugh I really don"t want to sew all of those little pieces together" then I watched one of the sewing shows and she had done a project where she put all of the squares onto fusible background and then folded and sewed them in rows, so I thought I can do that. The fusible web I used was a bit thicker then it should have been but it worked just as well and it has lots of body so it will not flop on the wall.
As for a pattern I saw it in a photo somewhere.
