Sandi and I have been collecting Fiestaware for several years now, amassing both the place settings as well as various serving accoutrements.
It's hard to find these accoutrements in some of the more interesting colors since you're usually limited to open stock at the department stores. Amazon to the rescue! I've discovered a Fiestaware store that stocks almost the entire spectrum of Fiestaware in almost the entire spectrum of colors. By the way, we collect Fiestaware because it comes in neat colors—making a dinner table full of the dishes more festive—and it's fairly affordable, unless you get into the rare pieces.
