Using these unfinished wood house shapes for your DIY crafts is easy. First, peel off the protective paper backing that came with the craft. This paper was there to protect the wood during laser cutting and shipping. If you need a hole in the shape, you can tell the seller the size and location of the hole, and they'll add it for free. You can choose from different sizes, ranging from 3' to 24', and thicknesses like 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, just message the seller. When it comes to maintenance, keep the wood in a dry place to prevent warping or rotting. If you want to paint or stain the wood, make sure the surface is clean and dry first. Have fun creating with these wood house shapes!
