When supporting the paper, hold the paper roll in one hand and the brush in the other. First, open the paper roll about 50 cm, aim it at the upper right side, then aim the right paper mouth at the lower twill edge, and gradually lift it with your left hand (don't lift it repeatedly to avoid uneven pulp marks and dye fading).

After the upper side is aligned, smooth the paper on the left and brush it on the right hand, from right to left, brush it with the development, and then put the supporting paper on the silk with a long brush diameter. If the length is not enough to hold the paper, you can use it to hold it. The slurry mouth of the joint should not be widened, and the slurry should not be too thick. Press the seam to 0. 2 cm is appropriate.
