Scoop ice cream into baking cups before the party and put in the freezer. When cake is served bring out the pre-made scoops. Brilliant! FYI-Use a Pampered Chef Bar Pan-the stone stays colder longer than muffin tins, thus the ice cream stays colder longer!
The tent effect was made with $1 plastic tablecloths cut in half lengthwise and tacked to the ceiling. It really gave the room a dramatic look for very little money. I also used the same technique to make the swags over the doors and archways.
