Dissolve 1 (3 oz.) package of Jello in 1 cup of boiling water. Add 1/2 cup of Jello to 1/3 cup sour cream and stir. Pour into 9"x13"x2" pan or 3 quart clear Pyrex glass bowl or pan. Put in refrigerator until set, about 45 minutes.

Add 3 tablespoons water to the rest of the Jello and pour on top of first layer. Let set about 45 minutes.

Repeat with 6 more boxes of Jello using different flavors and colors. (Use about 2 pints of sour cream.) (Red and green for Christmas.)
