Using your unfinished wood butterfly silhouette is easy. First, peel off the protective paper backing if there is one. This was there to keep the wood safe during cutting and shipping. Now, you can start your DIY project. You can paint it, add decorations, or use it as it is for a rustic look. When it comes to size, you have a great range from 3 inches to 36 inches to choose from. If you need a hole, just tell us where and how big. We'll add it for free. As for maintenance, keep the wood away from excessive moisture to prevent warping. If you paint it, a light dusting will keep it looking great. And remember, we made this product by hand in Pittsburgh with lots of care, so treat it well and enjoy your crafting!
