Don't be discouraged about making roses, it took me two class sessions to learn how to do my roses, plus I practice at home. I found out that if room temperature is too warm or too hot, roses don't seem to hold up well when making them. I use gumdrops with a coffee straw inserted at bottom and work with first petal while turning the straw counterclockwise. When I finished the rose, I put the straw with the rose inserted into a piece of form and waited to it firms a little before useing a tooth pick touching the top of the gumdrop to transport the entire rose onto the area of cake. I like to make the two tone color roses of any color. Just keep practiceing. It is not always the first try that you might succeed, but the finish tries will be the end results.
So sorry, I mentioned to use straws for the gumdrops, wrong straws. Instead use coffee stirs with rounded ends on each side. I brought my coffee stirs from a dollar store and they worked well. Again, I apologize for the mistake. Any questions, please feel free to ask. 
what do you tell people if they want to eat the rose?
