I've been taking the Mixed Media: Pen and Ink with Watercolor class on Craftsy
and have learned to draw with a dip pen and dry brush with ink.
This is a Nevada landscape done in dry brush with ink. I tried to show the depth of the landscape, but need to work on the amount of ink I use. Just a little bit goes a long way to darkening the image! I like using the dip pen, different for me and creates really interesting lines.
