When a painting is ready it needs to be mounted. This means that it first has to be made smooth and even, then glued onto another paper. While it is uncertain that the smooth surface itself is always something to strive for, the undoubted benefit is that colours stand out better and become more vibrant when the painting is mounted.
Once the painted image is smooth and glued to another paper, the question is whether to frame the image in a Western way, or continue mounting it as a hanging scroll – or as a vertical scroll. The art of mounting is quite difficult and I have a deep respect for those who master it. There are instructiuons on youtube and at the websites of some stores for artists’ materials, but I’m not sure I would try. It takes a lot of practice to get it right.
