Grandma Esther's Sea Foam Salad

We're having a Wilson family get-together this afternoon, and I was asked to bring a salad.  I'm surprising everyone with a salad their grandmother used to make when they were children.

Sea Foam Salad
2 cups boiling water
3 oz. lemon jello
3 oz. lime jello
1 small carton small curd cottage cheese (I think 12 oz.)
1 large container (16 oz.) cool whip
1 can drained crushed pineapple (20 oz.)
1 cup finely chopped walnuts or pecans

Pour boiling water over both the lime and lemon jello mixed together in a bowl.  Refrigerate until barely thickened.  Don't let this set up or you will have chunks of jello.

Add the remaining ingredients to slightly thickened jello.  Mix well.  Pour into a 9x13 pan and chill.
