Ebay - It's not actually really cheap, but if you scroll through "Luthier supplies - (search) Celluloid", they have a few whackadoodly patterns that I've never seen from LMII, Duncan, Warmoth etc.

And I know they're probably filling up unmarked graves behind the Chinese prison factory pumping them out (plastics are really quite poisonous, most of 'em) but... somebody's gotta buy it, right? :dontknow:
