Handwriting with different fountain pens.

I discovered that a relatively inexpensive 0.6 mm italic nib from Manuscript's Creative Calligraphy set works well with my natural handwriting, it looks "good" even when I'm just starting out.

But it took me a few hundred dollars of trying different sized nibs to really understand that for nibs in general, stroke width variation is through pressure, "pulling" the nib in parallel, and I really needed a stub / italic / calligraphy nib where line variation is through the angle.

Also, that my handwriting is really small, and finding any stub nib below 1mm is hard, until you know that it comes with the Manuscript set.

Beware, fountain pens are a rabbit hole.
