feathered hair band?

 how do you make a feathered hair band? i love those bands but they are ridiculously expensive. 

If you have a hairband that's got fabric padding you could simply jab the quills through the fabric and use dabs of glue to fix.

Alternatively, take a cheapy plastic one and a glue gun... Put down a blob of glue and set the feathers in it the direction you want them to sit, as it cools it should hold on to them. 
Are you wanting to make something like a fascinator?  If so, here are some instructions on making the base and layering the elements on it.
 
I had no idea they were called fascinators. Thanks for being my educational moment for today.
