To use this Christian wall art, simply find a nice spot on your wall, and since it's already wood - framed and ready to hang, you can easily put it up. Just make sure the hook or nail you use can support its weight. As for maintenance, keep it away from direct sunlight to prevent the colors from fading. If it gets dusty, you can gently wipe it with a soft, dry cloth. If you're not satisfied with the product for any reason, you have 30 days to get your money back. When waiting for the delivery, remember there might be small delays because the post office is very busy right now.
