I made one for a friend whose son has autism, he had one of his episode s and we gave him what was finished and he immediately calmed down. We did the Chan n els else but if I did another one it would be squares and rag quilt style. You need to use a lot of the little p e poets and I she purchased them on line. You need to sew very slow as the pellets shift around and get in the way. You may need a lot of needles.
