Oooh, I love this one. Another Peter Sheeler tutorial. Definitely more my style than the past several days. When I’m washing watercolor over, I generally use the pen Sheeler recommended, the Uniball Deluxe Micro Pen. It is an inexpensive pen with waterproof ink, and a nice steady flow. (a three pack for under $7 on Amazon) I assumed I’d need to use expensive art pens so it was a nice surprise to see how well these work. I really love them. Great for sketching and for everyday writing!
