Using this unfinished wood gingerbread girl shape is easy! First, peel off the protective paper backing. This was there to keep the wood safe during cutting and shipping. You can then start your craft project. 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. For different sizes, they range from 1 inch up to 36 inches in diameter. As for the thickness, we've got 1/8 (3mm), 1/4 (6mm), and 1/2 (12mm) cabinet - grade Baltic birch plywood. If you need a different thickness, just drop us a message. When it comes to maintenance, keep it in a dry place to prevent the wood from warping. If you paint it, make sure the paint is suitable for wood. Have fun with your DIY project!
