ChattanCat's wife says that if you are fortunate enough to have a wonderful sporran from the absolutely fabulous Turpin, you really don't need more than a black and a brown with some of the matching tartan flaps! Oh, and the adorable little coin holders are a must!
Of course, you HAVE to coordinate all of this with matching belts and sporran straps from the incomparable Cavscout. ChattanCat's wife is the fashion fascist, and she should know.
