I'm sure it depends...
are we talking about handwriting for personal notes or handwriting for something that other people are going to read?
my style, for instance, would change dramatically between these 2 types.
Like this when I'm sleepy.
More neat and less squiggly when I'm awake and using a proper pen. Also, more slanted and spaced, because my hand isn't too tired to do the larger movements.
pretty ****ty
