Using this unfinished wood scarecrow shape is easy. First, peel off the protective paper backing that's on most of these crafts. This was there to keep the wood safe during laser cutting and shipping. You can then start your crafting project right away. If you need a hole in the shape, just tell us the size and where you want it, and we'll add it for free. When it comes to the size, you can choose a diameter from 2 to 36 inches. The wood is cabinet - grade Baltic birch plywood in thicknesses of 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm). If you want a different thickness, let us know. As for maintenance, keep the wood in a dry place to prevent warping. Since it's unfinished, you can paint, stain, or decorate it however you like to fit your project. If you have any questions about the product, don't hesitate to message the seller.
