Making Shanwenkia Armor With Leather

[Buddahcjcc]

Not for SCA, just costume use, U have a fair spread of molds to put water molded armor onto, but what would the suggested thickness be? Im looking for it to look sturdy, not as though someone had made it out of paper. The armor itself is thought to have been mde with iron/copper.

For what it looks like I found this: http://www.armourarchive.org/essays/Shanwenkia.pdf

Any help would be great
