My cupcake was cut from the Straight From the Nest cartridge (which Kim can order for you if you want it) at 2 3/4". Because the little holes for the sprinkles were so small I opted to add some liquid pearls in Hydrangea and Key Lime to them instead. I attached my cupcake to my card with an action wobble.
I did a short video for you to help explain how I made this card. I first saw this idea on SplitcoastStampers. I hope the video helps you understand how this card works.
Here is a side picture of the finished card.
