I was asked to make the cake for my son's Pre-Kindergarten graduation. The theme is Nursery Rhymes, but I could also make a child-friendly graduation cake. Any ideas? Thanks

How about the rhyme:

What are little boys made of...snakes and snails and puppy dog tails
What are little girls made of...sugar and spice and everything nice

and doing little snake, snails, puppys, cakes, cookies, bows etc around the cake?

. . . you could use an open book theme . . . with several characters . . . jack and jill . . . cat and the fiddle . . . cow jumping over the moon . . . humpty dumpty . . . old woman who lived in a shoe . . . here is a link to a similar cake . . . hope it gives you some inspiration . . . http://cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1211487

A big 3D goose for Mother Goose, surrounded by grass, flowers, etc...? I don't know how I would make a gooses neck. I'm very curious about your cake now - and want to know what you decide & see pictures! This is going to be a really neat one!

I found a picture of a NR cake in a google search at the llink below. I clicked on the actual image it didn't work but maybe you can see enough of it to get the idea. It was for a baby shower but you could add a graduation cap to the characters heads. The pic was on the bottom row.

I know it's a lot of trouble but you will have to copy and paste the lines separately.
