Did you know that the That Darn Kat undies pattern has a version for boys with a real working fly. Just like with little girls undies happen to be a great way to use up fabric scraps for boys. These are just some of the pairs I made for Elijah. He loves how comfy they are and that they don't bunch up in his pants like boxers do. Technically the pattern only goes to a size 8 but since length is not an issue in undies these fit him and likely will for while.
