Rainbows are seasonally appropriate for every season! They never go out of style.
I love a repeating pattern, especially on food. Even better when it's done with something as delicious and natural as blueberries. Nothing fussy, no artificial coloring or hours slaving over perfectly smooth icing, just a fantastic and undoubtedly delicious polka dotted tower of celebration. I'll toast to that!

Hey bird! Why are you sleeping on my cake? I mean, you coordinate with it quite well and all but this isn't a nest, it's a dessert! You can't sleep here, you just can't. You're welcome to come to the party, just stay off the food okay?
