I will jump in.
Ti4019 Bast Alpha Garrison, and one of the few that is begining to work with Pepekura. Most of the people in my area have never heard of it,but I am working to show that there are other ways of costuming than ABS/ Hips/Resin and Fiberglass. I am working on an ATST helmet from Vagabond at the moment. All approved costumes are fan made and in the end screen accuracy and adherence to the Costume Reference Library (CRL) is the deciding factor.
Please get in touch with your local Garrison as noted earlier, but they may not be familiar with the process. There is a healthy mix of skepticism and hope that paper can hold up to the weekend trooping we do. But, as I tell them it will be as strong as I choose to make in, and that means it has to stand up to going out every weekend and surviving the ultimate test of a costume: Mardi Gras parades. 7 miles of drunken, unruly revelers throwing huge knots of beads BACK at you. Ouch. Got my "bell rung " this year.
After laying out around 3K so far in my costumes (TIE and ATAT Driver) this is a welcome change, putting ME in charge of completion date and final cost. I do believe some clones have been built and are displayed at Clone Empire.net but I do not know if those troopers have saught to clear thier armor for Legion (canon) use or use it for fun/variation armor.
