To make wooden puzzle, the first thing you should do is to decide which puzzle you want to make, how complex it should be and what are your capabilities for required wood working. You should carefully analyze the puzzle plan and very precisely cut and sand the puzzle parts. This is very important because even the minimal diggresion from the specified dimensions can lead to the problems during puzzle assemblage. The parts should be sanded very well, so they can slip easily during the puzzle assembling and disassembling, and to avoid hand injuries by wood splinters while playing with puzzle. If you wish you can paint the puzzle or apply finish. We recommend to make wooden box or a cloth bag to keep your puzzle, because the loss of even one part will take all the charm of your puzzle and it is very likely that it will thus become completely useless.
