Cui Wen Wei Zi pigment

No special treatment is needed, because propylene is a highly stable pigment with strong adhesion, hiding power and water resistance. It's okay to draw on canvas, or even wipe it with a wet cloth when it's dry. I used acrylic to paint on canvas shoes, and it was still quite bright after being washed n times. If you want to add some texture effect or grain effect to your painting, you can also buy texture primer to make the texture and various texture effects of oil painting.
