This patch is pretty rad, bright colors, neat shape, and detailed AF.
Can be ironed on but I would recommended to also sew into place so it sticks around for a while. Once attached to something securely could probably withstand a regular washer, likely not a dryer or high heat so may be best to dry clean only.
Measures 9" at it's widest which is pretty large. I would call it big enough for a back patch easily.
