So I'm about halfway done with this chessboard case for my hubby and it dawns on me that my pieces are large and easily broken. So I decided magnets would be a good call. What's the best way to go about it. A metal sheet under the wooden board and individual round magnets in the pieces or indivual magnets under the squares of the wooden board and in the pieces. Thanks for all your help...I'm so new at all this.
