Using these unfinished wood crafts is easy. First, peel off the protective paper backing. This backing is there to safeguard the wood during laser cutting and shipping. If you want a hole in your shape, just tell us the size and where you want it. You can also choose a different font by leaving a note with your order. When it comes to sizing, the crafts are available in diameters from 3' up to 36'. They're 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, just send us a message. As for maintenance, since it's natural wood, keep it away from excessive moisture to prevent warping. You can sand it further if you want a smoother finish. And remember, we're here to help with any questions you have, so don't hesitate to reach out.
