Glass jars or bottles provide a great base material for many crafts, but the least expensive option (reusing food jars or wine bottles that would otherwise be discarded) require me to do some surface preparation. Specifically, I need to get the labels off.
Right now, I'm just peeling and scraping the labels with a crappy old kitchen knife. But many labels are extremely well attached and there is a lot of glue and paper left. It seems like I can spend hours scraping and still have a sticky, dull, unappealing surface, which doesn't lend itself well to (e.g.) a clean, clear candle holder. Do I just need more elbow grease, or is there a method which helps remove labels and glue more quickly and cleanly?
