I've wanted to make a headband like this for some time!
It's super easy, hope you give it a try!
You will need: beads, needle, thread, super glue, scissors, old headband, ribbon, tulle, cups, paper, and a marker. The ribbon and tulle I got at the dollar store.
Trace circles of two different sizes onto your tulle. I used the top and bottom of a cup. (Make sure to use a whiteboard marker if you ever want to use the cups again.) Cut the tulle on the lines you drew. I made 6 circles of each size.
Fold the larger circles in half and then half again. Sew the pieces together one on top of the other. Space the folded circles to form a circle. For the smaller circles, I put one on the bottom without folding it and the rest on top, some folded and the others not. Sew the circles together
Sew on the beads. I used fishing line for this part so it would be less noticeable.
Super glue the ribbon on the headband. I put glue every couple inches. Then super glue the flower where it looks best.
Finished product! See it here in an outfit of mine.
P.S. Sorry about the not so great quality photos, my camera's kind of old.
