Using this unfinished wood winter hat silhouette shape is easy. First, peel off the protective paper backing that's on most of these crafts. This backing is there to keep the wood safe during laser cutting and shipping. Now, you can start your crafting project. If you need a hole in the shape, tell us the size and where you want it, and we'll add it for free. When it comes to size, you can choose a diameter from 2 inches up to 36 inches. As for the wood, it's cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) thickness. If you need a different thickness, just send us a message. For maintenance, keep the wood in a dry place to prevent warping or damage. Since it's unfinished, you can paint, stain, or decorate it however you like to make your project unique. If you have any questions along the way, don't hesitate to message us, and we'll be happy to help.
