Wallace's doors are usually asymmetrical. This "Circle Mode" design provides a dynamic composition that stands up to the rectangles around it. While Wallace does the metal work, she most often relies on John Hindman of Red River Restorations to fabricate the architectural doors. They are made of Spanish cedar, a wood that doesn't react to humidity and is very stable (so stable, in fact, it is used on cigar boxes). Collaborating with architects, craftsmen, installers, planners and other artists is a rewarding part of her work.
