Freeze the balls so they will stay firm while being dipped.
Dip your cake pop stick in melted chocolate before adding the cake ball to help it stay on the stick.
Use a deep container for the melted chocolate or candy so you won't have to move the cake pop around too much to get it coated.
The rest is just a matter of fun and imagination to take your cake pops from cute to creative with different decorating techniques. Enjoy!
