Has anyone made a tiered cake covered in rosettes in graduated rainbow colors? I have this idea in my head, but sometimes it doesn't work out quite right! Just wondered if anyone had done this and had oics they could share.

I thought about doing that a couple weeks ago for a cake I was doing for a kid's party. I went with something a bit more whimsical. I haven't had a rainbow fun/rosette elegant event to try it out for I guess.
