Using this unfinished wood wavy striped egg - shaped Easter craft is a breeze. First, peel off the protective paper backing that comes on most of these crafts. This backing is there to keep the wood safe during cutting and shipping. If you need a hole in your egg shape, let the seller know the size and where you want it, and they'll add it for free. You can use these eggs for all sorts of DIY projects. They come in different sizes from 3' to 36' and are made from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch thicknesses. When it comes to maintenance, keep the wood away from excessive moisture as it can warp or damage the wood. If you want to paint or stain the wood, make sure the surface is clean and dry. And always store the crafts in a cool, dry place to keep them in good condition.
