So this is what I've been working on for the past few days. Most of that time was trying to figure out how to actually get the text in the format I wanted (turned out I really did need to do it the hard way). Clothing designs are not my forte, but I do enjoy them.
Anyway, behold, System Reference Drip: Barbarian.
This test design has the entire SRD text for Barbarians (including the Berserker archetype). The text is shaped like an axe with brutal gouging on the red background.
This is a proof of concept more than anything else, and what's more it's on Redbubble (which is severely limited and frustrating to use), so quality is not assured. I'm still looking for a better on-demand printer that won't charge up front for hosting a design (which isn't mandatory, but these are test designs so I'll be going through a lot of them). But if you want to snag what is essentially a first draft, the shop is open and you get get there by following this link.
I'm open to suggestions on what piece of the SRD I should try to design after this (not what kind of design it should be made into, just the chunk of text).
