Phillip Jeffries wallcoverings are one of those things that are always in the office but I don't know that I've ever used. I do really love grasscloth though, especially the trellis pattern which also made an appearance here and I really want a reason to use a metallic grasscloth for myself. Perhaps someday.
Speaking of metallics, last night at a design event I saw some really cool wood flooring with metallic paints on top pulling out the grain. They are hard to explain but I will try to find a link and a picture. It's way too early and too hot right now.
