To make your Vi complete you need bid ass pauldrons and some leg armor. Take a look here to how to build te rest of the costume.
For this part I sadly left my documenting skills far away, meaning I forgot to take progress photos. But I managed to scavenge some.
For my Pauldrons I used first a shell of paper mache (strips of news paper and water with flour works) over a balloon. And then you cover this shell with expanding foam. Kamui have some great videos about this technique.
And carve away
The expanding foam is full of air pockets and to make it easier to make a smooth surface I'll cover it again with paper mache. And we are in luck, Kamui even has a video about this step too, how to cover with paper mache (since I forgot to take pictures)
And I like to cover my layer of paper mache with filler again to make a really smooth surface. And now sanding.
To make it easier for myself I covered the "side parts" of the pauldrons with cardboard instead of paper mache. And here stops my documentation of this project.
All the gold parts are sheets of cardboard. The round piece is thin foam mat (craft foam would work very well). Same goes for the piece sticking out on the end there. The gold on these parts are also cardboard.
As for the paint I have used the same grey as on the chest piece with a thin mist layer of silver on top. Battle damage is made with black and silver markers. And everything is sealed with transparent paint.
A small tip to make sure the collar of the jacket stays up, attach it to the pauldrons using velcro.
And this is how gorgeous it looks inside.
The knee armor
The base again is paper mache over a balloon. The bolts are paper clay and a strip of neoprene around the edge.
The leg armor
The legs are bent cardboard reinforced with plaster strips on the back. I made these before I discovered worbla and I would recommend that instead of card board as these will most probable crack after a couple of uses.
So this was a very short description on how I made the pauldrons and leg armor.
I still need to add some battle damage and a clear coat to the leg bracers, but in short this is one way to do it. Ask if I shall deepen on the steps.
