Patty, the walnut is a nice, "toasted" brown color. The pictures were taken in the solarium with full sun, so all these woods are a good bit darker when viewed in shady conditions. The sun is the culprit here. Same with the cypress pictures. The wood on the obverse is almost black. Unfortunately I just don't ever see any broad pieces of this water-soaked cypress any more. Most of these pieces will be around 4" wide, though they may be a couple of feet long.
I use coconut husks, with and without shells for mounting occasionally as well, Elaine. Needless to say I have to be "gifted" these from folks in FL. We don't have a lot of coconut trees here in NE Mississippi.
