Hiromi's Kozo Mix paper is a good substitute for Wenzhou Rice paper since it is sold out at retail price in the USA. It is just as advanced as wenzhou and shares almost the exact same properties during folding and shaping. There are both 68cm and 96cm sized rolls. While the roll is expensive, it is great value for what you get. (26 gsm)
Price: $36-44/roll

This is every folders dream paper. (20-60gsm)
