I could sell a pattern for this cribbage board, since it's mine. But it was made from part of a log from the woodpile, so it wouldn't fit any piece of wood you have.
This was another woodpile piece. Some articles call this 'found wood'.
The ways of attractively designing a cribbage board are amazing. The game has been around for centuries, and many of the old fanciful methods will still work. It's a challenge designing a board that is as good as the game.
In this case I bought the cribbage pegs at a hobby store, but they could have been cut or carved also. I just realized, they could be cut as a 3-D project on the scrollsaw. They'd be square pegs instead of round, but that could be neat. I'll have to play with that.
