Not terry e, but the flower with the stamens in the middle comes from Russian piping tips. Try google it in YouTube. Dozens of videos comes in butter cream, royal icing, & soap!
It's different animal than usual piping tips. Everyone says that in their cake video. Consistency is very important when it comes to Russian piping tips. When used in soap, the perfect time frame is quite short and not as forgiving as usual piping tips. It's either diarrhea or constipation for Russian piping tips. ( umm... Excuse my language, but English is not my mother language, and it's midnight so I can't come up with better description.) in order to let the stamens show, especially the one terry e used, it need to be a thicker trace but not so thick that the stamens won't come out so clean and beautiful. Rose and tulip Russian piping tips are a little more easy going than terry e's chosen one.
Sorry, these piping tips have no numbers and specific names,so you have to check the videos to get a better understanding.
