We bought 14 white T-shirts for sizes 8 - 10 (one size bigger because we knew they would shrink). We also bought special markers for T-Shirts and computer paper. We went online and on the Disney website we found Incredible Iron ons. We printed the Incredible Iron ons on the white T-shirts. They had so much fun seeing the Iron On Mr. Incredible t-shirts and they wrote their own names on the t-shirts and decorated them with those special markers. It was such a hit. All the boys wore them at the party.(they put them over their own shirts)
