I just posted a sketch on Urban Sketchers Twin Cities, that I did at the East River Flats, looking back towards the 94W/E Bridge. When I go for my walks, especially when it has been hot (anything over 75 is hot for me, but we've been getting some 80s), I don't like to take my regular journal because it means I have to carry it, or a pack containing it. Instead I just take a little Moleskine soft-covered notebook (gridded or plain pages).
These little notebooks are
about 3.5 x 5.5 inches and pamphlet stitched, with the pages in the
back half all perforated. One fits easily into my pants pocket with a pen (in this case a Staedtler Pigment Liner .7). I use these booklets to scribble notes to
myself that I then tear out and leave lying around, or to sketch in on
days like this. I tore the page out and stuck it in my journal, over a
piece of Canson Mi Tientes.
My walks are giving me an opportunity to work on my cityscapes. If I always have paper with me I don't have any excuse to not work on drawing buildings. And somedays I'm even lucky enough to find birds!
