Using these unfinished wood crafts is easy. First, peel off the protective paper backing that's on most of the crafts. This backing is there to protect the wood during laser cutting and shipping. If you want to add a hole to the shape, simply send us a message telling us the size and where you want it. For your project, choose the diameter that suits you, as these crafts are available from 2 inches up to 36 inches. Also, pick the thickness that you need - you can choose from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) cabinet - grade Baltic birch plywood. If the standard thicknesses don't work for you, just let us know. As for maintenance, keep the wood in a dry place to prevent warping or damage. And if you're storing it for a long time, wrap it in a soft cloth. Remember, these products are handmade in the suburbs of Pittsburgh, so treat them with care to enjoy their quality for a long time.
