Funny story about the color scheme:
An online friend of mine who does costuming (went as one of Vader's Shadow Guard at CV this year) suggested that, since I go by the nickname 'Pepsiman' elsewhere, I should make a set of Mando armor, and make it 'PepsiMando' armor.
So I did.
I was going to add red to the scheme (on the helmet and knee pads) but decided against it, and simply went with blue/black. Once I finished the helmet, I noticed that I took the color scheme from my Honda CR-V. Go figure.
Sadly I trashed the vest by putting it in the wash yesterday, instead of hand washing it, but I plan to make a replacement soon, with improvements (like a zipper instead of velcro on back).
Thanks for the suggestions as well, and thanks to the folks who I bought parts from over the past month.
