Bandana's are one of those multipurpose items that should be in every youth minister's tool kit. They can be used as blindfolds, to replace a short length of rope, as flags and to identify teams. They can be bought in bulk relatively cheaply or if you have someone in your church with a sewing machine and a little time they can be made from a few yards of cloth or even cheap sheets. If you can't find bandanas, you can always substitute cloth handkerchiefs, washcloths, or cloth napkins. Get enough for your entire youth group to have one each, and in different colors so they can easily be used to identify different teams.
