Ooh, I’ve been nominated in a few categories in this year’s Eagle Awards, including favorite penciler and favorite inker! Demo was nominated as well, for favorite American black and white comic, and favorite 2010 single story! How exciting!
I mostly use a Winsor & Newton Series 7 #2 brush, and india ink- but I also use pentel brush pens when I’m traveling, or just feeling too lazy to break out all the inking supplies, or am inking in bed. The Winsor & Newton brushes are kind of expensive, but for me they’re worth it. They also last a while if you take care of them. I don’t recommend starting on them though, decide if you like inking with a brush first before you dump a ton of money into supplies :)
I don’t use quills or pens much, but when I like using a G-Pen (a Japanese nib) and Faber-Castell pens I’ve found to have the best line quality and ink of any pens I’ve tried.
