For my large framed work, which can be about 24 x 24" up to about 27 x 35," I use a wood frame with a metallic-look finish that I would describe as "pewter-like," in that it is silvery but not too shiny. It has a texture and nice lines that go well in traditional decor as well as industrial chic decor. The mat is a single white cotton rag mat that is extra thick, adding some dimensionality to the presentation.
