Apropos of nothing, looking at the inscription on the outside of the package, I'm struck by how beautiful handwriting was in 1912. I'd like to get that back somehow.
Buy a good fountain pen, write slowly. Start by getting cheap pens, preferably those with interchangeable nibs to see which nib size you prefer using. When you know which size you like (for most people it will be medium) get a decent pen and nib and carry it with you. I have a vintage Parker 51 and some oldish German pens. Modern Japanese pens are quite good though nibs can be narrow for Western taste.
You get splotches everywhere and they often dry up for no apparent reason.
