Carnival Birthday!

Here is an order for carnival-themed items for a 5th birthday party (for 60 guests!). At first, the request was for Ferris wheel cookies (the little seats were 2-toned blue and raised). Anyone have any tips on how to pipe a perfect circle?

Then, a 2-tiered cake was added. It's chocolate sour cream cake with vanilla Swiss meringue buttercream filling, topped with dark chocolate ganache (that's one secret to straight edges!), and then, marshmallow fondant. This was the first time I made stripes, and it turned out great! The circles were placed randomly. I am glad the cake was well-received! I love it when everyone's happy! :D

Happy Birthday, Francesco!
