Most Helpful Girl
I write with a pen. If I make a mistake I just cross it out.
Pens are easier for me because I can be a bit heavy handed when I'm writing fast which makes pencils a nuisance as they will just break. Plus pens are naturally darker than pencils so that stops me pressing down just so I can see the marks I'm making.
If I'm just doodling I will use a pen for that too, but if I'm actually making an effort with a drawing, generally I will use a pencil so I can add more detail and shading. Pens are a little sucky for shading I've worked out. Plus smudged ink looks terrible. Smudged charcoal or lead gives the look I want.1
