i had a couple long strips of cloth left from the edge of a skirt i cut a bit too long, so i decided to try making a headband with it.
measure the head of your child so that the length of the elastic is about 2" longer than her crown. then cut the 2" strips of cloths to twice the length of the elastic.
sew the edge of the of the cloth about 1/4" in from the edge. make sure that there is enough space for the elastic between.
turn the headband inside out. kids can be a great help here. it helps to use a chopstick to push the fabric through.
