Making Jello layers is much more simple than it seems, it just takes some time. You prepare your bottom layer first, by dissolving the package in boiling water, stirring in cold water, and putting it in the pan or container of your choosing. You refrigerate it until it's almost set, usually about 45 minutes. Next you prepare your next layer the same way and gently spoon it over the first layer, then refrigerate for 45 minutes. You repeat until you have all the layers you desire.
