Using these unfinished wood body - builder shape crafts is easy. First, peel off the protective paper backing that's there to safeguard the wood during cutting and shipping. You can use them for a variety of DIY projects. If you need a hole in the shape, tell us the size and where you want it, and we'll add it for free. As for maintenance, keep the wood in a dry place to prevent warping. Since it's unfinished, you can paint, stain, or varnish it according to your project needs. If you're using it for a long - term display, avoid direct sunlight to prevent the wood from fading. These crafts are cut from high - quality Baltic birch plywood, so treat them gently to get the most out of your DIY.
