Thanks for the advice. Personally, when I do ink, I just use a ballpoint pen. It turns out looking okay, to me anyways. The thing is, I'm afraid of inking. I spend a lot of time on my art, and I don't like risking it getting ruined. When I'm inking, I'm constantly afraid I may make a mistake I can't erase, on a piece of artwork I spent hours on just to get right. I do so much erasing, it's not even funny.
Any tips on how to avoid ruining an entire piece of art while still inking it? That would help a lot. Especially since most of my art is in dire need of being inked and finished.
