I wrote my junior thesis in high school in gold Crayola color pencil. I got extra credit for it. Bizarre, I know, but I couldn't decide between sky blue and red-orange, so. :T
Now, I'm a cross between mechanical pencil and ballpoint pen. I'd love to own a fountain pen, but the thought of messing up scares me. I only use the ballpoint for writing claims and the like at work.
Mechanical Pencil, what I need to do is just buy the leads.
I'm using 0.7 too so it's pretty common.
Since I'm doing Accounting, I use Mech Pencil so I don't need to liquid paper everything.
I typically like pens. I don't know why maybe it just looks neater or more official or something. My least favorite is definately chalk. I hate the stuff. It kills my ears whenever someone uses chalk. It makes me grit my teeth.
I also like mechanical pencils but sometimes they make a skreetchy noise that I can't stand.to me it's like nails on a chalk board
