Using these unfinished wood Claddagh shapes is a breeze for your DIY projects. First, peel off the protective paper backing that's on most of the crafts. This was there to keep the wood safe during cutting and shipping. You can customize these shapes by adding a hole if you need one. Just tell us the size and where you want it. These shapes come in different sizes from 6 inches up to 24 inches, so you can pick the one that suits your project best. They're made from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch thicknesses. If you need a different thickness, let us know. When it comes to maintenance, keep them in a dry place to prevent warping or damage. And if you're using paint or other finishes, make sure the wood is clean and dry before applying. Have fun creating with these Irish - themed wood crafts!
