Here is the table set up - I went a little crazy with the rabbit food theme - we had salad, berries and cream (just like Flopsy, Mopsy and Cottontail!), blanched asparagus, tea sandwiches, scones and devonshire cream, and those cute little champagne grapes. We served lemonade in pretty tea cups. For flowers I used some potted plants and herbs I already had, a few bunches of inexpensive glads, and best of all, several bunches of Swiss Chard in vases.
And here is the cake - complete with sugar pansies and garden fence, sugar vegetables and butterflies, and a sugar Peter peeking out of the watering can. I don't have a good picture of the girls in their dresses, but I made them all three little dresses out of the Beatrix Potter fabric. The queen loved it, and thought it was the best birthday EVER! (of course, she only has last year to compare to, since I am pretty sure she doesn't remember the first two!)
