I am doing a cake for an autism fundraiser for 200 people and the theme is pinwheels. Does anyone have any great ideas....I thought about making a sheet cake and a couple of cakes on pedestals on the side....but am drawing a blanc on the design..........

anyone?

Well, what about for the sheet cake a pinwheel design from a quilt? Something like that:



You can make the middle section with only few "blocks" and colors.
For the cakes on the side, either smaller part of the main cake or for round cakes perhaps something like the head of this flower:



Shamelessly grabbed from internet.

yes, I did see this one too....thank you

My thought was pinwheel wind spinners in a garden. Some fondant, some frosting on the sides, even some paper ones to give some motion to your display.

Pinwheels are easy to make from paper, you should be able to create the same thing in fondant. -

There are also pinwheel cookies and puff pastries.

How fun, first thought is to practice making a pinwheel out of paper. Then, Make one out of fondant. When you bend each flap over, insert a wad of bunched up plastic wrap to help hold the shape. Once all flaps are folded, use a kitchen skewer or tooth pick to "pin" all together. You can then, after
dried, snip off and make a fondant button or ball for the center. Can either lay over a drinking straw or a bubba straw to look like the handle. Would be cute laid over the top of a cake etc. Hope this helps, sounds so fun, I may have to try it myself.
