The weekly urban sketching challenges continue in our flickr group. For sketchers, they are a good incentive not to forget the sketchbook at home and to look for specific subject matter. And for everyone else who appreciates location drawings, the themes give us the opportunity to see a similar subject through the eyes of sketchers around the world. The week of June 10-16 the theme was glass steel and concrete modern architecture. Here are three of the submissions. Check out the fun discussions, and see the rest of the images on this link.
