These unfinished wood snowflakes are great for winter decor and DIY projects. To use them, first peel off the protective paper backing. Then, you can paint, stain, or decorate them as you like. You can hang them on the wall, use them as tree ornaments, or incorporate them into other craft projects. If you need a hole in the snowflake, just tell us the size and location. When it comes to maintenance, keep them in a dry place to prevent warping. If they get dirty, you can gently wipe them with a dry cloth. We cut these snowflakes from cabinet - grade Baltic birch plywood, so they're of good quality. If you want a different thickness, let us know.
