Using these unfinished wood spooky shape crafts is easy. First, peel off the protective paper backing. This was there to keep the wood safe during cutting and shipping. You can use them for all sorts of DIY projects like Halloween decorations or unique wall art. 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. For sizing, they come in diameters from 1' up to 36', so pick the one that fits 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. To maintain these crafts, keep them in a dry place away from direct sunlight to prevent warping. When you're done crafting, you can paint or stain them as you like.
