Using your unfinished wood marching band shako hat silhouette is easy! First, peel off the protective paper backing. This paper is there to protect the wood during cutting and shipping. Then, you can start your DIY project. If you need a hole in the shape, send a message to the seller with the size and location you want, and they'll add it for free. When it comes to maintenance, keep your wood craft away from excessive moisture to prevent warping. You can use a mild wood cleaner if it gets dirty. Remember, these crafts are made of cabinet - grade Baltic birch plywood in different thicknesses (1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch). If you want a different thickness, just let the seller know. Enjoy creating your unique marching band shako hat silhouette!
