I've been faffing around with a Sailor fude nib I bought a few weeks ago. Fude nibs are bent upwards so they provide line variation as you change your pen angle, similar to a brush or brush pen. I'm still pretty bad at using the nib intentionally, but it does cool stuff if you mindlessly draw with it. You can block in color really fast with it, which is awesome but also requires frequent dipping, even with the built-in feed it comes with, because that is a fuckton of ink.
I think fude lines are bold enough to stand on their own, but I plonked the marker on top to make things more fun!
I've been thinking about my sketchbook in terms of "how" instead of "what": I pick a medium or color palette I want to experiment with or improve at and dedicate the entire spread to that. It's helped me avoid succumbing to perfectionism-induced decision paralysis because I just think about cool stuff I want to try instead of getting stuck on making a pretty picture.
I've avoided dabbling in ink drawing without drafting with a pencil underneath because the thought of putting ink on the page without a plan fills me with irrational dread, but that changes now! (The avoidance is changing. No guarantees on the irrational dread.) This is also my first time doing plein air drawing, so there's excitement all around.
