Using this unfinished wood castle tower shape is easy! First, peel off the protective paper backing that's on most of these crafts. This backing is there to keep the wood safe during laser cutting and shipping. If you need a hole in your shape, send us a message telling us how big you want the hole and where to put it. You can also ask for a different font by adding a note to your order. When it comes to sizing, you can choose a diameter from 3 feet up to 36 feet. The wood is cut from cabinet - grade Baltic birch plywood in thicknesses of 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm). If you need a different thickness, just drop us a message. To maintain your craft, keep it in a dry place to prevent the wood from warping or getting damaged. Since it's unfinished, you can paint, stain, or decorate it however you like to fit your medieval fairytale project. And don't worry about waiting long for your order - we'll ship it within 24 hours, or it's free!
