I was introduced to grayscale markers last year and I can’t rave enough about them. They are more satisfying to draw with than pencil in my opinion due to how smoothly they flow and how quickly you can draw with them. It feels like painting more than drawing and seems like an ideal way to plan a painting.
I found some old sketches at my parents’ home…from over 20 years ago. They were mostly done for a sketching class I took in college and after that. It’s so nice to find these now that I’m back to making art again.
