Thanks for the question, and the answers.
I always thought a Jawa would make an easy (no face, no armor, small size, etc.) full-size replica to make.
I think that may have to happen.
it´s quite easy to get a good result, i took the robes Chris offers from time to time on ebay or on his website. HERE
try contacting him, he is one of the nicest persons and always willing to share his knowledge.
hopefully he will find the time to finish his work on the jawa related section on his website soon.
