Using this unfinished wood salt box house shape for your DIY project is easy. First, peel off the protective paper backing that's on most of the crafts. This was there to keep the wood safe during laser cutting and shipping. You can customize it by asking us to add a hole in the size and location you want. When it comes to sizing, you can choose from 3' up to 36'. As for the thickness, we offer 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, just shoot us a message. After you're done with your project, to maintain the wood's quality, keep it in a dry place away from direct sunlight. Avoid using harsh chemicals on it. And if you have any questions along the way, don't hesitate to click the 'Message Seller' button and we'll help you out.
