A bit over a year ago, I was toying with the idea of making an Imperial Fist w40k Space Marine army. I love their stubborness, I'm a sucker for yellow and they had just received their own codex.
I don't generally like using decals, but freehanding those fists on the shoulders of every marines sounded quite tedious. Not only that, but the fists logos for the Imperial and Crimson Fists look way better in relief.
So I made myself a pattern for making closed gauntlet logos. It works for greenstuff and painting. With a little modification it can be used for the House Steiner or Iron Hands logo, as well as any fist-based rebellious emblem for any setting.
