I periodically get bored with my dinnerware and change it out. Not often, but Salvation Army/Goodwill get a donation every 15 yrs or so, LOL.
Currently I do have 2 Corelle patterns - one for dinner, one for salad plates - both white with black trims. I do like that they reheat in the MW but have just enough of a curved rim to be easy to pick up, even using a potholder.
I bought them to go with one of my last remaining "holdovers" from the days when I used to throw formal dinner parties every month or so. I had gold-rimmed, white Mikasa bone china, but when we moved to this home I stopped throwing sit-down dinners as everybody was going to potlucks. Fortunately, a friend fell in love with our china so I gave it to her - full service for 12.
When I used the Mikasa, I liked to have different bowls (I often did Chinese banquets, so needed rice bowls, not European salad bowls) and dessert plates. Fritz & Floyd had some wonderful dessert plate patterns. One was a black porcelain with two beautiful white magnolia blossoms and leaves. The finish finally started to get dull so I gave them up a few years ago.
The other F&F I still have, and is in perfect condition. I bought the Corelle patterns specifically because they look okay (not perfect, but good enough) together with the F&F:
This is F&F's "Fish and Shell" pattern by Cathy Hardwick - black background and metallic gold trim. It also came in blue, red, and green background colors.
Again, as I still do as much Asian cooking as Western cooking, we have bowls that were bought separately - large white porcelain "ramen" bowls, and individual 8-oz white porcelain ramekins with opposing handles (good for French onion soup, etc.).
