Just a mix i made the other day:
purple fiebings,inferno,pottasium permaganate and ox blood fiebings.
i dont think the fiebings completely mixes with everything, the ink kinda changes colour and stains like a bitch :rolleyes:
oh yeah, when your using pottasium, dont use too much because it will fuck up your pen, ink and nib...it wont dissolve properly and will leave grit inside the nib and shit...not nice
