Tartan has the right idea. Have your brother choose a couple of contrasting solid colors to use as the background fabric, then find the largest patch to determine the size of squares you will need, sew the patches on the squares and make a beautiful quilt. When you quilt it, you will need to go around the patches with the quilting - patches are so thick and have that glue-like backing that you will probably have a problem with breaking needles and lousy stitches on them if you try to quilt over them. When you sew them on the fabric, use a larger needle (like a jean needle) to keep your stitches clean and your needles whole.
