Striped Jello Salad(Can Be Used For Dessert) - cooking recipe

Ingredients

4 small pkg. jello (your choice of flavors; at Christmastime, I use reds and greens! I wonder why?)
2 c. milk
1 c. sugar
2 pkg. (envelopes) unflavored gelatin
2 c. sour cream
2 tsp. vanilla

Preparation

Each package of jello will be made with 3/4 cup boiling water and 3/4 cup cold water.
There will be four jello layers with filling between each jello layer.
It is time consuming, but the end result is worth it.
