Using this unfinished wood dinosaur skeleton shape craft is easy. First, peel off the protective paper backing that comes on most of these crafts. This backing is there to keep the wood safe during laser cutting and shipping. You can then start your DIY project right away. If you need a hole in the shape, just tell us the size and where you want it, and we'll add it for free. As for sizing, you can choose from 3 feet up to 36 feet. Also, we use 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, reach out to us. When it comes to maintenance, since it's natural wood, keep it away from excessive moisture to prevent warping or mold. You can use a light wood cleaner if it gets dirty. Just enjoy creating your unique dinosaur skeleton crafts!
