Wow – two artworks in one day!
Taking a stab at waves in black and white. A sketchy technique seemed to work ok for this.
I used a Uni-ball F12 .05 point gel stick pen for this. They used to make them in a .07 point, which was the perfect gel pen for me, but they stopped. I guess I was lucky to find the .05’s (at jetpens.com) but I long for the .07 days. I still have a couple that I am judiciously hoarding. I know…pen nerd.
