Sketching with another artist who has different preferences for subject is a challenge. I like to draw dense clusters of objects, while Donna focuses on the play of light in the spaces between objects. Urban Sketchers Seattle met on Vashon Island Friday. Having never been there before, Donna and I spent way too much time wandering around, comparing locations. We finally settled where she had a view of the Sound, while I drew the nearby clump of mailboxes.
