Make your own fairy wings; here is what you need:
2 wire hangers
Pair of tights (whatever color)
Elastic (to make the arm bands)
I looked online and found an excellent tutorial HERE that I thought I'd put up because no pictures were taken of these being made. The only differences are that she used the extra part of the tights to make the arm bands, and my Mom (who made these) used elastic. My Mom also wrapped thick ribbon around the middle part of the wings to hold in the elastic and cover up the hangers as well. She decorated them with fabric glitter glue.
