Great for birthday parties where you want to give each guest a favor. For each child you will need a small block of wood wrapped with a very long (several yards) piece of yarn. Make sure each child has a different color yarn. Just before the party unwrap the yarn by winding it back and forth, over and under and through the furniture in party room. At the end of each piece of yarn tie a favor. As the guests arrive give them their block and let them wind up the yarn as they follow the string to the favor.
