> Write with FOUNTAIN PENS. Ideally on thicker paper, with something soft below (like more paper for example).
I love fountain pens. Well-made ones are elegant and feel good to write with. I love the look and feel of certain kinds of permanent black and blue-black ink that you can’t find for ballpoint.
They were extremely useful in dealing with hand cramps at a time I was doing a lot of mathy stuff for work (tens of pages of derivation a day for a while). They retrained my hand to not push on the page so hard and not grip the pen so hard. That eliminated most of the problem.
That said, they have had no effect on my handwriting. Which was bad-to-mediocre before and remains bad-to-mediocre now.
