I am making a poured ganache covered cake and i'd like to pipe curlicues on the side. I can think of how to drop the string in order to make the tear drop/raindrop shape. Is it possible?

I can't visualize what you trying to do...you want upsidedown teardrops on the side of the cake?
 

AI want to make curlicues with the tear falling down. If I use RI I'm not sure how to pull the string.

I was looking up  curlicues and there are so many designs!!  do you have a pattern for it?   something like this?  http://thesparklestudio.blogspot.com/2010/04/blog-hop-tea-cup.html
