My son did the same thing with his T-shirts before I got them. I added iron on lightweight interfacing and squared them up. I took several of the smaller patches and sashed (sometimes on angles) until i got a usable size block. I often put four logos together in a block. I used all red scraps. Then i put together as usual. With a black sashing red/black school colors Think of this as a bonding lesson. You will be his favorite aunt.
