Using this unfinished wood Christmas tree station wagon shape is a breeze. First, peel off the protective paper backing that comes with the craft. This was there to keep the wood safe during laser cutting and shipping. If you need a hole in the shape, let the seller know the size and where you want it placed, and they'll do it for free. When it comes to the size, you have a great range to choose from, with diameters from 3 feet up to 36 feet. As for the thickness, it's cut from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) cabinet - grade Baltic birch plywood. If you need a different thickness, just send a message to the seller. Maintenance is easy too. Since it's unfinished wood, you can paint it, stain it, or decorate it however you like to fit your project. Just keep it away from excessive moisture to prevent warping. And if you have any questions along the way, don't hesitate to message the seller.
