Some months ago, I uploaded a drawing of the front of our house. This time, I drew the back of the house---in the same style. Last time, I used a Pigma Micron 005 pen, this time, I used a Uniball Signo Gel pen---which made the drawing a bit looser. This is a large house in the Pacific NW Modern style (a late 70's incarnation) with characteristic big windows, skylights, and jutting angles.
