Today I made Kozo paper. Kozo is a traditional Japanese papermaking fiber also know as paper mulberry. First, I cooked the fiber in soda ash. Then I used my new rotary cutter and mat to trim the fiber into 3 inch pieces. From previous experience, I know that leaving fibers too long and throwing them in the hollander will result in fibery dreadlocks and overbeaten but uneven pulp. Problem solved! I only had to beat it in the hollander for about 20 minutes because it is such a delicate fiber. I also could have beaten it by hand, with a mallet or bat.
