This set is using the Just Buzzin By set.
When you slowly open the card the middle window opens to reveal yet a 3rd bee inside the little window.
This is scheduled for a class this month but the class is already full.
If you want to make it and see how really easy it is to line all these little windows up Super Easy, then call me and we can schedule a class with some of your friends. When things slow down a little.. maybe after the first of the year, I will put a tutorial with step by step pictures on the process. Jan Tink has a tutorial on her blog but it leaves out how to effortlessly and quickly cut out the circle for the whisper white top of the card.
