Using these unfinished wood axes and helmet shapes is easy. First, peel off the protective paper backing that's on most of the crafts. This was there to keep the wood safe during laser cutting and shipping. If you want a hole in the shape, just tell us the size and where you want it, and we'll add it for free. You can use these shapes for all sorts of craft projects. They come in different diameters, from 2 inches up to 36 inches, so you can pick the right size for your needs. When it comes to maintenance, keep the wood away from excessive moisture as it's natural wood and can be affected by water. If you're not using the craft right away, store it in a dry place. And remember, these are cut 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.
