Here are three headbands I made for my nieces. (ages 9-17) They're just plastic headbands with ribbon braided onto it. I sell these for $6-8.00 depending on the ribbon I use. Currently I only have two plastic headbands left to braid onto but if I hear of some interest I will buy more to make some custom headbands. These use 3/8" ribbon so if you have something in mind...just remember the width is 3/8".

This headband has two purple ribbon, one pink and one checkered ribbon with a few colors of purple and pink on it.

This one has green striped ribbon with some butterfly ribbon and white as the outlining ribbon.

This headband uses green with pink edged ribbon, pink, apple green, and pink with green dotted ribbon.
