The pen and ink sketches that have been posted are great and have inspired me to give it a try - with a rollerball pen. Yesterday, the phone was the most interesting thing in clear view on my desk. After doing the phone, I pulled the stapler out of the drawer and just started in sketching. Ended up with floating office supplies.
Maybe I should get a fountain pen with permanent ink so I can brush some watercolor over sketches. Any recommendations for the type or brand to buy?
