Well, that's good to know haha At least I don't sound like a jerk haha Glad you understand my point ^_^
Anyway, making it look like it's actually made out of blood, the ONLY way, is a hadened liquid. The only hardened liquid that STAYS hardened, is resin..I think there are lighter weight resins that should be good and obviously light, but I have zero experience with resin or casting. Essentially you could make a wooden one (if you have either scrap wood the right size and thickness) and buy the mold making stuff and make a mold to cast it in..Then either get rid of the wood one or sell it..Or keep it I guess..All depends..lol
