I can't believe this is all this old. I haven't kitted up in Jango in years but my daughter is now making a Boushh kit so I came back to the site to look around.
Glad to see others still working on costumes. It is a great hobby and and I have not done enough of it in the last few years.

I used purple, pearl gray and blue......plus bleach washing it to get the weathering right
