  1. Cut tulle into your desired size. I cut each of my tulle pieces 1.5 ft long x 7-8 inches wide, double for each color (1 for the unicorn headband and the other 1 for the unicorn tail.) Note: Measurement width varies depending on your toddler's age and how poofy you would like the headband/tail to be.

  7. For unicorn tail - measure elastic to your child's pants or child's waist (cut elastic a little longer for extra room in case of any adjustments needed.) Each fabric scrunches together, create loop and knot to elastic (as pictured).
