Does anyone have any ideas how I can make a bow for a present sheet cake without having to make one out of fondant?

Couldn't you just draw one an fill it in with a star tip or a plain tip. I can see it in my head, but can't find a pic. Good Luck- Katie

You could pipe a dress bow (the one with 2 loops and a knot) with a rose tip (104). Wilton has instructions on their site.

You can make one out of gelatin.
