I've realized that when I use cheap pens on hotel stationery, my handwriting looks terrible, probably because the surfaces are too smooth? Other than fountain pens, are there other alternatives that give more tactile feedback?
It's only half a joke: having to regularly dip the pen in ink, be mindful of how much ink you have, having to swiftly wipe it once in a while to avoid drying ink (& flow issues), forces to slow down & take "micro-breaks".
This benefits the handwriting, but also the quality of the study. And is surprisingly relaxing.
(so called "crow-quill" nibs are relatively cheap, available, carry a fair amount of ink)
If you are stuck using a very smooth paper, I would suggest either a fiber-tip or a drier gel pen. Gel pens with a clicker (e.g. Zebra Sarasa) tend to write drier than those with a cap (e.g. Uniball Signo). Also try a fatter tip. Although this may not be acceptable in many situations, a soft pencil may provide even better control on smooth paper.
Will give the Zebra Sarasa a try.
