First you will need a stretchy headband like the one in the picture. ( I bought mine from the dollar store)
Once you have the headband you want to use, cut it at the seam. Then you want to wrap it around your wrist to measure how big you want it.
Once you have your size, you want cut it to that size. I usually fold the ends in and sew it shut so the ends don't fray. But that is not necessary.
Then you want find your item you are going to secure your bracelet with. I choose button for my bracelet. If you do buttons just snip a small hole and push the button through to make your hole fit your button.
Then you can sew or glue whatever it is you used to secure your bracelet.
Now you are ready to enjoy and show off your new bracelet!
