Using these reindeer - shaped unfinished wood ornaments is super easy. First, peel off the protective paper backing that's on most of the crafts. This backing is there to keep the wood safe during laser cutting and shipping. You can then start your DIY project right away. If you need a hole in the ornament, let the seller know the size and where you want it, and they'll add it for free. When it comes to sizes, you can choose from 2' to 36'. The ornaments are made 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, just send a message. For maintenance, keep the wood in a dry place to prevent warping or damage. Since these are handmade in the Pittsburgh suburbs, handle them with care to keep their quality intact. If you have any questions during your project, don't hesitate to message the seller.
