Using these unfinished wood marshmallow heart silhouettes is a breeze. First, peel off the protective paper backing if it has one. This paper is there to keep the wood safe during cutting and shipping. You can then start your DIY project right away. You can paint the hearts, add decorations, or use them as they are in your craft. If you need a hole in the heart, let the seller know the size and where you want it, and they'll do it for free. When it comes to maintenance, keep the wood away from excessive moisture as it might warp. If you paint it, use a good - quality sealer to protect the paint job. These hearts are made from cabinet - grade Baltic birch plywood, so they're sturdy, but handle them gently to avoid any accidental breaks. And don't forget, if you have any questions during your crafting process, just message the seller for help.
