I did these yesterday in a clothed figure drawing workshop. My teachers all hate the ball-point pen I use, but I find it to be extremely convenient and ready-at-hand. It also makes me commit to my lines and eliminates any desire to erase.
I was born and raised in the Denali Park area of Alaska and now live in the capital city of Juneau with my husband and two young children. I have a MFA in Visual Development from the Academy of Art University in San Francisco. I'm avaliable for freelance work. Email me at firstname.lastname@example.org.
