Printing a limited edition on silk

I have always been curious about working with silk. One of my new projects is working on a hair drawing and a design to be printed on 100% silk. I am planing on making a limited edition of hair scarves. Last week I was at Kala Art Institute making a few tests and the results are quite optimistic. I printed my first sketches directly on the silk and I am now researching on how to make the silk washable. I found a formula online to pre-coat the fabric and make it durable and I will experiment with it in the coming week. I hope to have the scarves ready for the next Open Studios in San Francisco Mission District, in April 2014.
