Place tall glasses into a muffin tin tilted or on a baking sheet this just makes it easier to move them in and out of the refrigerator.) Equally, divide blue JELLO mixture between four cups. Place in the refrigerator for 15-20 minutes or until it sets.
Meanwhile, start preparing white layer by mixing one packet unflavored gelatin in a small bowl with ¼ cup cold milk. Heat remaining milk, ¾ cup, over high heat until just before boiling, remove. Do not scald. Add the sugar and vanilla. Stir until dissolved and mix with cold milk and gelatin mixture. Stir until well mixed and allow to cool.
Evenly pour white gelatin over blue layer. Place back into the refrigerator for 15-20 minutes or until it starts to set.
Next, mix the cherry JELLO with 1 cup boiling water. Allow to cool for 5-10 minutes. When white layer has set, equally divide red over the white layer. Return to refrigerator to set for 3-4 hours.
Do not garnish until ready to serve, especially if it is a hot day!

Having an adults only party?? Make your Red, White and Blue JELLO Cups vodka laced. To modify, soak fruit in vodka in an airtight container for 12 hours, drain. For red and blue JELLO layers, use only 1/2 cup boiling water to mix gelatin. Allow to cool slightly before stirring in 1/4 cup vodka. You can also purchase alcoholic whipped cream if you so choose.
