Although I am not directly interested in English calligraphy, I feel it is necessary to practice it using copybooks to improve regular handwriting. I feel my pencil handwriting could definitely be improved, if not in legibility then in speed and comfort, mostly for timed essay-writes in school. I've done some searching of my own and have found some popular copybooks to be Spencerian, George Bickham's
The Universal Penman, and Copperplate. I've also skimmed through the
Handwriting Aids sticky, but while it provides some great examples and methods, it doesn't recommend copybooks. My question is: what is a good copybook to start with if my goal is developing pencil handwriting that is both quick and legible?
