I will be making a similar cake for my cousin's bridal shower. My question is how do I get the ruffles to be as shown in the photo?

And what kind of technique was used to make the ruffles? maybe ball tool or a tooth pick? I have been practicing the ruffles using the frilling tool, but each time they turn out a little different. I will practice more!! This will be my first fondant ruffle cake and I of course want it to look fantastic! 

Any tips are greatly appreciated!
