The silk I used was from RSM, I think it is Chinese silk, and is supposed to be pre shrunk. I have ordered silk from Sig, it is Esaki, Japanese silk. Only problemis whenever I order it, they are out of stock. I ordered 2 yards last, waited almost a month. This time I ordered another yard along with more dope, for a Sig Ryan ST I'm starting and back ordered again. I really don't care for the chinese stuff, although at 12.00 a yard, it is half the cost of the Esaki. Then again, maybe the Esaki silk won't need as many coats of clear.
