French instruction manual, 1900, page 24, large French Roundhand (called simply Ronde in French, but it differs from English Roundhand, which is why I'm specifying). Pen nibs and how to write with them. Roundhand perhaps took a differently-shaped nib? (Roundhand, by the way, is alternately spelled Round Hand. There seems to be no consensus on the favored spelling as far as I can tell.)
Finishing up my final project for Italic Hand class - a portfolio of Italic & variations. From bottom to top: Formal, chancery, flourish, pointed, and lightweight. Definitely the most challenging hand thus far! per Christopher Jones
French instruction manual, 1900, page 3, Cursive. Heights of letters, width of the thick parts (which only works modernly with a calligraphic style nib on a fountain pen or the equivalent) and the slant of lettering. Penmanship exercises where just as demanding as they are now, plus you were expected to learn more than one style of writing.
