Using these unfinished wood yellow tang shape crafts is easy. First, peel off the protective paper backing that comes on most of the crafts. This backing is there to protect the wood during laser cutting and shipping. If you need a hole in the shape, send a message to the seller with the size and location you want, and they'll add it for free. You can use these crafts for a variety of projects. They're available in different diameters from 1' up to 36' and made from 1/8 (3mm), 1/4 (6mm) or 1/2 (12mm) cabinet - grade Baltic birch plywood. When it comes to maintenance, keep them in a dry place to prevent warping or damage. If you want to paint or stain the wood, make sure the surface is clean. The seller ships these items within 24 hours, so you can start your project soon. If you have any questions, don't hesitate to message the seller for help.
