My brain is doing its own thing again. When I saw the thread title, the first thing in my mind was the clap on, clap off commercial that airs around Christmas. And I have a clapper, but never thought about using it for stubborn seams on quilts.
How you use it. The top area is like a very narrow wood ironing board for seams that are hard to get to. The pointed part is for points. The bottom compresses seams. You press, usually using steam, then set the clapper on the seam and push down to compress the seam are. Haven't used mine since I made my last suit.
