Using these unfinished wood Brunei country - shaped crafts 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 cutting and shipping. You can use these crafts for all sorts of DIY projects. If you need a hole in the shape, let the seller know the size and where you want it, and they'll add it for free. As for sizes, you can choose from 3' up to 36'. When it comes to the thickness, they're cut from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, just send a message. Maintenance is simple. Keep the wood in a dry place to prevent warping or damage. And if you're painting or staining the wood, make sure to do it in a well - ventilated area. That's it! Have fun with your DIY project!
