Soak a rag or paper towel in rubbing alcohol. Cover the sticker you want to remove with the alcohol-soaked rag. Let it sit for about 30 minutes. The sticker should wipe clean afterward—but if it doesn't, gently scrape away any remaining residue with a razor scraper.

If you have a physical photograph or drawing that you want to make into a sticker, you can scan it onto your computer or upload a digital photo. Format this file on Photoshop. Paint, Word, or Adobe Acrobat, then print it onto the sticker paper. Draw directly on the sticker paper with pens, pencils, or even paint.
