I have decided to start a new set on flickr with drawings done while my toddler sleeps. If everything goes right, she will have a nice 90 minute nap and everyone would be happy. If not, I'll settle for 30 minutes. As long as I have my pocket sketchbook and some drawing media. There is always a pen or a pencil in my bag(s), but the Lamy, the Noodler's Flex Nib and the Microns travel from bag to desk to kitchen table and therefore they're not always on hand.
This sketch was done with a ballpoint pen. The lady was a perfect model: she barely moved during my sketching. Maybe she was tired of pulling her cart uphill from the big grocery store half a mile away.
10 min walk to the park + 40 min sketch + 10 min walk back home. Baby slept all the way. Lady was still there when I left.
