I just looked at them for a minute on the 'zestydishes' website but it didn't look like they have all the colors in the square style?
Maybe I just didn't look hard enough. I have the round and like the more traditional look about them, and all the colors! I have 9 different color place settings now but plan to add more:)

I bought four sets back in September. I was hesitant to buy a complete set because I was afraid maybe the corners would chip or break. I have the red set and so far so good. The plates are kind of dipped around the edges. So it's hard to rest a knife on the edge when eating. The bowls can only be stacked by two's. They won't set straight on top of each other. I see a few small scratches from someone being too aggressive with cutting their food. I do prefer the mugs to my old "non fiesta" set. I also have the smaller square salad plates and the oval bread plates.

All in all I am happy with the square sets. The red really shines on my dark granite. They have a heavy feel which I like in dishware. The fact that they're made in the USA is a plus. I plan on buying more and just doing away with my old everyday dishes. But I can't decide if I want a different color.

I was tempted, but resisted. I have collected tons of regular Fiesta (vintage and post 86), and decided they might discontinue the line before enough "great" colors come out. One of the beauties of Fiesta for me is that it has been made so long -- and will likely continue to be made -- that I can always find new, and new-old pieces ;-).
