Get a styrofoam board, round or square, or even one that can fit in the basket.
Cover styrofoam with material. Make leaves & fondant flowers or get ready made ones :) you can also decorate them with Buttercream. What ever you prefer ;)
Place the cupcakes on the decorated board and stick the skewer through them.
That's what holds them down ;)
Then decorate your cupcakes
I love buttercream ones :)
