Has anyone ever patched their Uggs themselves? I dont really want to take them to the cobbler, but the back seam on one of my boots is coming apart. I tried to sew it myself, but I think it needs to be patched. I wear them for comfort - not fashion - and always under pants, so I dont care about a visible patch. Suggestions? I googled Ugg repair kit, but apparently no such kit exists - only "care" kits, which are useless.
