Well, not learning how to write from scratch, but rather, learning how to write with a fountain pen. You see, as a lefty, there are all manner of things working against me successfully using a fountain pen. You have the whole push-vs-pull hand movement, but more importantly, there is the issue of ink. Specifically, of ink drying times.
I had lot of the same doubts, being a lefty, when I got curious about fountain pens. But I got over it. The most important thing until you either learn some techniques or get over it is to go for ink and paper combinations that limit the dry time. The Noodlers Bernanke inks are the best. The only places I even noticed dry time when I used it was with paper that are known for long dry time.
Noodlers Bernanke and Leauchttrum1917 is a solid combo.
