Of all art supplies, I find etching cream to be the most magical. Ok, maybe magic is an overstatement, but it certainly packs a big wow. I discovered the stuff a few years ago, and I must say, it's hard to go wrong, as long as you follow the directions. Here are a few ways to use craft with it…just be sure to wear rubber gloves; it burns when it touches your skin!
