Bottlecap Shamrock Keychain

"It's the week of St. Patrick's Day, so what better time to share a DIY that incorporates Guinness beer bottle caps and shamrocks. I consider this to be a bit of a hardware store craft, because that's where you can get almost all of the tools and materials for the project. This is a nice project to make in bulk because it's inexpensive and it doesn't take much more time to make a half dozen than it does to make one."
