Using these unfinished wood fairy shapes is easy. First, peel off the protective paper backing. This is important as it was there to keep the wood safe during laser cutting and shipping. Then, you can start your crafting project. If you need a hole in the shape, just tell us the size and where you want it, and we'll add it for free. These shapes come in diameters from 2 inches up to 36 inches, so pick the size that suits your project best. They're made from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) thicknesses. If you need a different thickness, let us know. As for maintenance, keep the wood in a dry place to prevent warping. When you're done crafting, you can use a wood sealer to protect your finished piece and make it last longer.
