Using these unfinished wood Grand Bahama Island country shape 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 laser cutting and shipping. You can use them for all sorts of DIY projects. If you need a hole in the shape, just let the seller know the size and where you want it, and they'll add it for free. When it comes to sizing, they're available from 3 inches up to 36 inches, so you can pick the one that suits your project best. The wood is cut from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch thicknesses. If you need a different thickness, reach out to the seller. As for maintenance, keep the wood in a dry place to prevent warping or damage. Since these are hand - made in Pittsburgh's suburbs, you can expect good quality. If you have any questions along the way, don't hesitate to message the seller.
