Using this unfinished wood swimming - shape craft is easy. First, peel off the protective paper backing that comes on most of the crafts. This paper is there to keep the wood safe during laser cutting and shipping. If you want a hole in the shape, let the seller know the size and where you want it, and they'll add it for free. You can use these crafts for various DIY projects. They come in sizes from 1 foot to 24 feet and are made of cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch thickness. If you need a different thickness, just message the seller. When it comes to maintenance, keep the wood away from excessive moisture to prevent warping. You can sand it further or paint it as per your project requirements. And remember, the seller ships within 24 hours, so you can start your project soon.
