I'm in the same boat, but I'm going for more of a classic appearance. There's loads of tutorials out there for the Begins mask (Just like every Joker tut out there focuses on Ledger's performance), so it's a matter of which one you find easiest. It should be rather easy already, as it looks crudely sewn, adding to his scare factor, but honestly I don't think that the burlap would be that irritating. Of course it's a tolerance thing.
Have you Googled any tutorials?
Red Sniper (TF2)
Wreck it Ralph (Wreck it Ralph)
Tommy Vercetti (GTA Vice City)
