Heart filled with flattened bottle caps (beer, coolers, hard cider, etc). Bottle Caps are tacked onto half-inch plywood using a wire brad; no glue was used. Dimensions are approximately 16 inches wide by 14 inches long. I used 151 bottle caps. 150 are different. See if you can find the bottle cap with the duplicate. Hang this heart in your game room and challenge your friends to find the one with the twin! Caution: there can be multiples of one brand but each CAP is different; except, of course, for that ONE. Hanger in back is balanced and the hole has been notched so it hangs flat against the wall.
