I'm having some trouble with getting my Pearl-ex mix to flow. Given I've not tried using the ink with the nibs listed on the back of the packaging (I got the 'new' calligraphy set with *whoopie Joi's Rose Gold), perhaps that's the problem? I tried using the Zebra G, with a mixture ratio according to the packaging. I added more water and the ink is flowing better, but does more water = more gum arabic? Should I add a little more of it in the mix? I'm not too sure what gum arabic does (I know it's a binding agent, but does water affect that?).
Any advice much appreciated! Thank you.
