Using this unfinished wood Kokopelli shape for your craft is a breeze. First, peel off the protective paper backing that comes with it. This backing is there to protect the wood during laser cutting and shipping. You can use it as is, or if you need a hole, let the seller know the size and location, and they'll add it for free. When it comes to sizing, it's available from 3 inches up to 36 inches in diameter, so pick the one that suits your project best. The wood is sanded and made from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) thicknesses. If you want a different thickness, just send a message to the seller. As for maintenance, keep it in a dry place to prevent warping or damage. And if you have any questions during the crafting process, don't hesitate to click the 'Message Seller' button for help.
