Using this unfinished wood dwarf shape for your crafts is easy. First, peel off the protective paper backing that's on most of these shapes. This backing is there to keep the wood safe during laser cutting and shipping. If you need a hole in the shape, tell us the size and where you want it, and we'll add it for free. You can choose from diameters between 2' and 36' and thicknesses of 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm). Just let us know if you need a different thickness. As for maintenance, keep the wood in a dry place to prevent warping. You can paint or stain it according to your project needs. If you have any questions, don't hesitate to message us.
