Heather of Dragonfly Designs shares a series of extensive step-by-step photo instructions for making several Angry Birds Halloween costumes. They are sized for a family to wear, but can be adjusted to fit an all-adult or all-child group. Seeing a whole pack of Angry Birds and green pigs going down the street on Halloween would make my heart happy. I guess I need to start sewing immediately! [via @zakkalife]
