Just found this lovely vid about dyeing with natural dyes and the traditional dyeing process in India which leads onto the actual authentic block printing process. Presented by Shilpa Rath. The traditional method is with Indian vegetable dyes. This is how we make our blocks too - some of the carpenters may well be the same guys that we use at The Block Printing Shop. Love seeing all the natural products that they use to do their natural dyeing.
