I have been practicing Architecture for 20 something years and I think some of the best time I have enjoyed have been those times when I have the opportunity to sketch. I was reading a blog recently that encouraged Architects and Designer to get back to the practice of sketching for which I could not agree more. There is just something that comes through a sketch that you don't experience when you design on computers. There is a visceral connection that exists between paper, pencil, and hand that you don't experience any other time in a project. Not that you don't enjoy the practice of seeing a clients dream realized, but in that moment of interpretation and manifestation is the realm of the sketch. I plan to use the tool more often.
I have attached some sketches that I have worked on recently that I really enjoyed.
