Query: cheap, light, and easy

does the job, although some darts can poke through a little. the hole is also a bit oversized, leaving a ring of exposed wall. but if you position it so the exposed 1/2 inch or so is on the bottom of the board, it will be very hard to hit the wall, due to the downward dart trajectory. it's light enough to just use double sided foam tape to stick to the wall, hanging it on the dartboard isn't that good of an idea. i'd especially recommend it if you don't plan on missing the board much but want to just spend a little bit more to be safe.
