Fude for thought
Two drawings of sunflower bouquets in brown ink and alcohol marker. The marker was used in single-colored rectangles surrounding each of the flowers. The drawing on the right features black eyed susans and uses yellow, light and dark green, and orange. The drawing on the left features lilies and uses yellow, pink, orange, and peach. The author is bad at flower identification and can't tell you much about the rest of the flowers.
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!
