One Denver art trend from last year was the less-is-more aesthetic. Many venues took on this topic, but Space Gallery's Lines and Grids stood out. That's because everything in it was reduced to its most basic expression, with the works all but invisible aside from the paper or canvas on which they were done. The exhibit was organized by Marks Aardsma — a master of the light touch herself — who invited like-minded artists to join her for the fourth rendition of a series on the subject. Among the Colorado artists on board were David Sawyer, Tonia Bonnell, Sophia Dixon Dillo and Scott Holdeman, whose work was shown alongside that of artists from across the country. The show really proved how little it takes for some artists to convey a fully formed visual message.
