I am having to make a Christmas themed cake. It can be up to two tiers. I am making it for a class and it is required that the cake be covered in fondant, have a pulled/blown sugar element, and a modeling chocolate element. I have several different ideas running around in my head, I'm just not sure what I could do. I was thinking about maybe making a cookie jar, or making it look like a gift box, but I'm not sure.

Christmas tree?

Santa Claus?

Sanity clause?

You say it's for a class. Barring any church/state separation issues, Nativity scene?

There is a cool tutorial on how to do a "candle" fondant cake somewhere on this site. You could do candles and then have blown sugar ornaments and some kind of decorations (maybe pine cones?) made with the chocolate around the base.

How 'bout a blown sugar snowman with pulled sugar carrot nose and stovepipe hat, etc.? Choc clay children and dog around him and choc. clay spruce tree with icing "snow" on branches.
 

Maybe a snow globe (made from the pulled/blown sugar)....just an idea :)
