I filled up a fountain pen, after taking a break for most of last year. Oh dear, my handwriting has regressed again. Also, I am no longer sure which pen of mine is the that gives the best line. I like a line that varies in width a lot, depending on stroke direction.
I like writing longhand with a fountain pen. I am not in a habit of doing that, and I am lacking inspiration of what to write. A fountain pen is just awkward enough that I'm not sure I want to carry one with me everywhere.
