Using these unfinished wood New South Wales state shapes is a breeze. First, peel off the protective paper backing before you start your DIY project. You can add a hole to the shape by telling us the size and location. These shapes come in sizes from 3' to 36', so pick the one that fits your project best. They're made from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch thickness. For other thicknesses, just send us a message. Since they're unfinished, you can paint, stain, or decorate them however you like. When it comes to maintenance, keep them away from excessive moisture to prevent warping. And if you have any questions during the process, don't hesitate to message the seller.
