Upon first inspection, this ugly garment appears to be made of irregular patchwork. When you discover the garment, roll 2d6 to determine how many patches it has. You can wear the garment to detach a patch and transform it into a single cheap supply. New patches can be sewn into the garment by expending a consumable supply. It takes 10 minutes to sew a patch, and you can only sew as many new patches per day as the strength of the magic item allows, and no more than the maximum number of patches the garment had when it was first discovered.
