Quick Question: I want to cover a child's birthday cake, 3 tierd, in Fondant. I want to do multi-colored stars around the border, but am not sure if I can do that with Buttercream or Royal Icing. Also, if it will work, and stick and stay in place, any tips on attachment? I had asked my Wilton Instructor, but she was unsure!?!

Thanks for all the help!

Yes, buttercream and royal both stick to fondant quit well. If you stick fondant to fondant then you use a little dab of gumpaste glue.

Editing to say it is quite shocking your instructor does not know about this

Do you mead "stars" as in cut outs or drop stars with a bag and tip?

oh sorry...I meant stars with a bag and a tip...like around the border edges.

Oh yes, they will stick just fine!
