Using these unfinished wood vampire bat shapes for your crafts is easy. First, peel off the protective paper backing that comes on most of the pieces. This backing is there to keep the wood safe during laser cutting and shipping. 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. You can choose from different diameters, ranging from 1' to 36'. The shapes are made 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, let us know. When working on your project, keep in mind that these are hand - made products with attention to detail. To maintain them, keep them in a dry place to prevent warping or damage. If you have any questions during the crafting process, don't hesitate to message us, and we'll be happy to help.
