For your party menu: Given the majority of the party will be undertaking creative challenges, setting up a buffet for the kids to enjoy as they are hungry may be just the ticket.
Snack and finger foods would be perfect. Popcorn balls, cheese and crackers, veggies and dip, pite bread and hummus, chips and dips and any other types of snack foods would be perfect.
After the Project Runway Challenge is over serve up an Ice Cream bar with different flavors of ice cream and toppings for the kids to enjoy together.
