How long do you want to spend learning acrylic painting?

The smallest palm is as big as the palm of your hand, and the largest is half the height of a person. It depends on your needs, or if you are willing to use paper to draw. For the most common sketch paper, buy a water-soluble tape yourself. Apply water on the glued side of the tape. The four sides of the white paper are pressed flat and mounted on the board. Then just do the same painting, just cut the paper when it dries.
