Subarmalis designs?

[Magnus]

Based on the ones Graham posted alone, I would say the only one that would qualify as leather would be the fourth one, or upper right (tomb of acceptus). The others are depicted hanging only as textiles can. Even the last two, appear to be quilted, and puffy, I don't think you can get the same effect with leather. It looks as though the artisan went to some effort to depict that.
