It's a great idea, but it took me a few minutes to 'get it' and that was only after I read Keens post, which was after I watched the video. The pinmoor looks just like my earplugs and if I wanted to use those I could get bags of them at any sporting goods store (used for ear protection when shooting guns) or smaller quantities in the drug store. But I actually like the chunky foam craft pieces idea the best. I'm going to check Hobby Lobby for them and compare prices for bulk earplugs. Thanks to Bella for posting!!
