Using your unfinished wood elf hat shape is easy. First, peel off the protective paper backing. This backing was there to keep the wood safe during cutting and shipping. You can customize it by adding a hole - just tell us the size and where you want it. The elf hat comes in various diameters, from 1 inch to 36 inches, so pick the size that fits your project. As for maintenance, keep it in a dry place to prevent warping. You can paint or stain it to give it your personal touch. If you have any other questions, don't hesitate to message the seller.
