Thanks to those fancy cakes pictures on Pinterest, everyone assumes that cake decorating is a piece of cake. But if you had any experience whatsoever, you would know that this is not the case.

This latest clip from America's Test Kitchen states that before you even bring out that piping bag, you should always trace out the design on your cake with a toothpick first. This allows you to gauge on how much surface area you have and is easier to smooth over should you manage to screw up. Be sure to watch the video above to see how this works.
