i have a staicker maker from kmart - you feed whatever you want to be the sticker in one side, and it comes out self adhesive. not the cheapest option, but we used it to make labels for wine bottles for our wedding three years ago - soooo simple and they came out awesome. there are refill catridges too

well, i'm assuming they still have them!

i last used it to make a hand print of DD's into a sticker to go in DH's birthday card so i have the packaging for replacement cartridge sitting here if you want more details
