Using this unfinished wood Ethiopia country shape is easy. First, peel off the protective paper backing that comes with most crafts. This backing is there to protect the wood during laser cutting and shipping. Now, you're ready to start your DIY project. If you need a hole in the shape, let us know the size and where you want it, and we'll add it for free. When it comes to sizes, you can choose from 3 inches up to 36 inches. The wood is made from cabinet - grade Baltic birch plywood in thicknesses of 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm). If you need a different thickness, just send us a message. As for maintenance, keep the wood away from excessive moisture to prevent warping. You can also apply a wood sealer or paint to protect it further and make it look even better. And remember, if you have any questions, just click the 'Message Seller' button and we'll be happy to help.
