For my medium-sized framed work, which can be about 12 x 12" up to about 16 x 20," 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. The example here shows one of the Zen Impressions pieces I have printed on Japanese mulberry paper.
