Using this unfinished wood Finland country shape is a breeze. 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 however you like. If you need a hole, just tell us the size and where you want it. The shape comes in different sizes from 3 inches up to 36 inches, so pick the one that suits your project. You can choose from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you want a different thickness, let us know. To keep it in good condition, avoid exposing it to excessive moisture. When not in use, store it in a dry place. Enjoy your DIY Scandinavian crafting with this great product!
