I haven't had a lot of time to actually work on my ROTJ Royal Guard costume besides doing a lot of research and gathering the parts, but here is a quick update:
Collected all the items to start and finish my RG build. This includes patterns, fabric material for inner & outer robe and cloth gloves, all the components of the force pike, fiberglass RG helmet, red visor material, and the paints.
I am done with the outer robe, but still need to line it with the same burgundy velvet material that I will use for the inner robe.
I just got my helmet in the mail. This is what the package looked like when I got it


Luckily, the actual raw helmet was fine.


I need to fill in some of the pits and lighter fiberglass areas with bondo and smooth it, but overall I'm happy with the helmet.
Now that I have all the parts, I should be able to complete my Royal Guard costume fairly soon. I just need to stop further work on my other unfinished 501st costumes and concentrate on this one.
