Using these unfinished wood s'more shapes 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. If you need a hole in your shape, let the seller know the size and where you want it. The wood pieces are available in various sizes from 3' to 36', so pick the one that suits your project. You can choose from different thicknesses: 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. Just message the seller if you need a different thickness. For maintenance, keep the wood in a dry place to prevent warping. If you want to paint or decorate the wood, use regular wood - friendly paints and supplies. The seller is based in the Pittsburgh suburbs and hand - makes these products, so you're getting a high - quality item. If you have any questions, don't hesitate to message the seller, and they'll be happy to help you.
