Momme is a Japanese measurement of silk weight. It's so many grams per yard, I forgot what exactly.
I bought the silk from a tie dye supply shop along with the dyes, colored the silk, and then doped it on. I used 60:40 thinner to dope for the first part, and once the weave started to fill in I switched to 50:50 thinner:dope. Easy peasy! I used nitrate dope, for weight management and less shrinkage. There are a couple spots that I've been threatening to hit with some butyrate dope, because they refuse to tighten up. Mostly just the elevator, and no one will notice that being wrinkly at 90 MPH.
