Using this unfinished wood Kauai Hawaiian Island shape for your DIY craft is a breeze. First, peel off the protective paper backing that comes on most of these crafts. This was put there to keep the wood safe during laser cutting and shipping. If you need a hole in the shape, tell us the size and where you want it when you place your order. You can choose from sizes ranging from 1' to 24' and thicknesses of 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, just send us a message. For maintenance, keep the wood in a dry place to prevent warping or rotting. When you're done with your project, if you want to display it, you can give it a light dusting every now and then to keep it looking nice.
