If you'll like to become a freaky ruffle decorator like me here is a tutorial so you may do so...
Cake ( already crumb coated)
Buttercream or Frosting of your choice
Turn table (Lazy susan)
First thing is to have your cake crumb coated very lightly. This is because if it is not coated the crumbs will begin to stick to your piping tip and or start to fall off, and also if your ruffles aren't to close together the crumb part wont show thru.
Now repeat the same step until you decide where you like to stop.
The more ruffle you add to your cake the more beautiful it will look.
On the top you may want to leave it with out the ruffles and add some detail or what ever you like, but I just decided to keep going and going....
Cupcake Shoe and Sprinkles, what better things to add???
Hope you enjoy making ruffles on everything you can get your hands on too! Good Luck with it and if any questions just leave me a comment.
