really need ideas for a grad cake for a little boy in kindergarden. the school colors are green and white,but what decorations would you use?

Simple - a mini doll skirt grad hat and a roll of fondant OR wafer paper for a scroll. Make the writing big letters and maybe even use bubble letters.

thanks kakeladi, i like the idea for the scroll and the big writing. maybe make the letters in different colors?! i am really very new to decorating so i really wasnt sure what you mean when you said "a mini doll skirt grad hat". how would i do that?
