Elf wore a hole in his threadbare hand-me-down jeans, so I sewed a patch from a way-too-small but destroyed favourite of his. I saved the zippy pocket from an old pair of camos. I turned the jeans I was repairing inside out and pinned the patch where I wanted it. I sewed it on, flipped the garment right-side out and cut the "window" where the patch is. On denim patches, this looks even more cool when the very edges fray a bit and you have a multidimensional look. But... I used the camos because some little boy loved those pants and that pocket. Looks a bit odd, but it will last him through the winter and he likes 'em.
