How do you make Japanese Calligraphy paint?
The process is pretty much the same with Sumi painting. You simply grind a water paint stick against your stone instead of ink. (Fineartstore.com has a nice assortments of primary calligraphy and Sumi supplies if you cannot get them in your hometown, or there are some very dedicated shops like Silverdragonstudio.com, artmam.net, Paragon-art.com, and Orientalartsupply.com where you can find some really great items to assist you in developing your own way with the Four Treasures.
