1. Cut away collar and sleeve. "Open" up the tee.
2. Cut long stripes. Try it with 1" stripes, see if you like the thickness after you pull the material, so that it curls up.
This was a first time for me too, so it's really just an experiment. I cut up both tees, and ended up with quite abit of excess material.
3. Arrange the stripes in a way that you would like it to be worn. Necklace, bracelet, etc.
As you can see, I braided mine too.
I shall try again when I get hold of more tees... ;)
