Using these unfinished wood mother - of - the - bride shape crafts is a breeze. First, peel off the protective paper backing before you begin your crafting project. If you want a hole in the shape, tell us the size and where you want it when you place your order. For a different font, just leave a note. You can choose from diameters between 3 inches and 36 inches. The wood is cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) thickness. If you need another thickness, don't hesitate to ask. As for maintenance, keep the wood in a dry place to prevent warping. Since it's unfinished, you can paint, stain, or decorate it as you like to fit your project. If you have any questions along the way, reach out to us and we'll be happy to help.
