Using your Unfinished Celtic Triskele Shape Craft is easy. First, peel off the protective paper backing that's on most of these crafts. This backing was there to keep the wood safe during laser cutting and shipping. Now you can start your project. If you need a hole in the shape, tell us the size and where you want it. You can also choose a different font if you want. These crafts come in different diameters, from 3 inches up to 36 inches. They're made of 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 send us a message. When it comes to maintenance, keep the wood in a dry place. Avoid exposing it to too much moisture as it can damage the wood. And that's it! Have fun with your crafting project!
