I have been working on the iron banner cloak and sash, to make it light and move around more like the game i used Linen. But due to the nature of the material used, you need to make sure you atleast double fold to make sure it doesnt pull apart. That is what I use, but to each their own, the Linen will rip easily i think so choose based on use (show or in combat) =D
And thanks for the drop box =) very cool and organized
