As any canvas painting already has a wooden frame, you can hang it very easily on a wall. All you have to do is hammer nails in the wall, depending on the size of your wall canvas painting and hang it up. Also, you do not necessarily have to go with a framed canvas painting as there are ways to decorate unframed paintings as well. If you have a small canvas painting, one is enough, or you could go for multiple if the size is bigger.
