Using this unfinished wood bat - shaped craft is easy. First, peel off the protective paper backing that's on most of these crafts. This backing is there to keep the wood safe during laser cutting and shipping. You can customize it by asking us to add a hole. Just tell us the size and where you want it, and we'll do it for free. As for sizing, you can choose diameters from 1' to 36'. The wood comes sanded, so it's ready for you to start working on. If you're using tools on it, be careful of the lightly burned edges from cutting. When it comes to maintenance, keep it in a dry place to prevent warping. If you need a different thickness of wood than the available 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm), just send us a message, and we'll see what we can do. Enjoy your crafting!
