Using these unfinished wood swordsman 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. You can use these crafts for various DIY projects. If you need a hole in the shape, let the seller know the size and location, and they'll add it for free. When it comes to sizing, the crafts are available in diameters from 2' up to 36'. You can choose from 1/8 (3mm), 1/4 (6mm) or 1/2 (12mm) cabinet - grade Baltic birch plywood. If you need a different thickness, just message the seller. To maintain these wood crafts, keep them away from excessive moisture to prevent warping. You can also sand them further if you want a smoother finish before painting or adding other decorations. Have fun with your crafting!
