They are my favorite to use in the spring and through the summer.
Here are some additional pictures that better show the detail. These are designed by Susan Branch for the Lenox Company. Called "A Proper Tea," they were available a few years ago. The pitcher was a gift from one of our daughters and is not part of the grouping, though it does fit with the Lenox pattern. The bowl is called a berry bowl.
China in the background is Strawberry Fair by Johnson Brothers.
I hope spring is arriving where you are!
