Using these unfinished Bolivia - shaped wood crafts is easy. First, peel off the protective paper backing that comes on most of the crafts. This backing is there to keep the wood safe during laser cutting and shipping. You can use these crafts for all sorts of creative projects. If you need a hole in the shape, let the seller know the size and location, and they'll add it for free. When it comes to sizing, the crafts are available in diameters from 3 inches up to 36 inches. You can choose from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) cabinet - grade Baltic birch plywood. If you need a different thickness, just message the seller. To maintain these wood crafts, keep them in a dry place to prevent warping or damage. Since they are hand - made in the suburbs of Pittsburgh, you can expect high - quality craftsmanship. If you have any questions along the way, don't hesitate to message the seller, and they'll be happy to help you out.
