She hasn't gotten back to me yet - but I can't imagine it would be a problem since she posted the instructions online at another forum
I think I followed her instructions pretty closely - her etsy store is called fyrebrand and she used to sell pixie skirts that are like these tutus, but without the tulle. Anyway, here's what I did:
You can use a woman's headband - the stretchy fabric kind - I used one made by Goody - as the waist band.
I cut my strips of tulle & ribbon so they were twice as long as I ultimately wanted them to be.
Take a piece of tulle or ribbon and fold it in half. You want it positioned under the headband - folded end up closest to the band. take the loose ends and pull them through the folded end, around the band. Pull tight. REpeat. I put my tulle on first, so it would hold the ribbon up.
that's it - No sew, and SUPER easy!
