Hey!
I needed some as a give away and cut some
triangle puzzles. I made them 4" high, cut from 1/4" European Beech plywood. I made 8 of them and mixed the puzzle parts so the grain should not be a hint.
These are simple and fast to cut, nice little gift.

I also did cut a turtle puzzle animal. cut from 3/4" European Beech.

I will try to double this wood next time to have a 1.5" board and try to cut it with a FD-P#3 (worked fast and easy on the 3/4").
