So I decided to JUST DEAL WITH IT.
Yes, the ink will bleed. But I want to continue with this pen and this paint.
I think if I am aware of the fact that the ink will bleed I just need to be more careful about my brushwork. The past few sketchbooks I have filled have been pure black and white since I have been separated from my paints for so long. Seeing colour back in my sketchbook just makes me feel....happy. Another piece of my soul puzzle in place!
