I think it is to early to think about a therapy quilt as it might offend if it isn't needed. I think I would look for neat fabrics like pizza, motorcycles, scout badges etc. and cut simple squares to do a hospital bed size quilt. The boys that age can sew the squares together (you can quilt it)and if you put a light backing on it, they can write messages of encouragement or get well wishes with Pigma pens from themselves or the whole troop all over the back.
