mixing inks?
hey i have a kick ass bottle(3oz bingo style dotter), good size and i put a nice chalkboard eraser nib on it. Now i just bought some sanford higgins eternal permenant black ink and some winsor and newton gold metallic ink. Can i mix the 2 inks together in my bottle, and if i can how much of each ink? This is the first time trying to make a mop and i could use a bit o' help, before i fuck it up.
