Art Party from Catch My Party - You can create colorful and cheap decorations by adding streamers and balloons to a light fixture. This would be a great way to decorate the ceiling for Workshop of Wonders VBS!
Rainbow Punch Pinata-I like this SO much better than the mad scramble for candy where someone always winds up crying and/or hurt I picked this because it seems like a very creative idea for a child's party instead of doing just a regular pinata.
Walk the plank - a great idea for our pirate party! We had a Pirate swimming party and put the across the baby pool. The kids had to walk the plank without falling in the water. It was the best part of the party.
