How do you prevent the batik wax from dripping when you are painting with a tjanting tool, or a "batik pen"?
Batik Tjanting Tool - Too Many Drips!
Practice is key.
After awhile you get to know what to expect, and it's just something that takes a little while to master, but it's not impossible. You will get it.
A couple of tricks have to do with how close your fabric is to the wax pot. I try to keep mine as close as possible when I'm painting, without actually touching, of course. And although I do work fast, sometimes it's worse the faster you are painting. Let me know in the comments if you guys have gone through that too! Do you incorporate your mistakes into the design? Because that's actually something that I do.
The other thing is that looks are deceiving. I actually do make lots of mistakes.
