Step one:
Cut your shirt so there are strips of fringe hanging down. Try and make them kind of even, don't worry about having the lines be completely straight. With the bead weighing them down the bad sides will fold in. Make sure to cut so that all of the strips start at the same point in a straight line, like the picture below.
Step two:
Step two is to put your bead on and pull it up, like the picture below.
Tie a knot, and pull it tight. Slide the bead back down after.
Tips!
Tip one:
You may run into an issue with the bottom of your strand being too big. Roll it diagonally and slide the bead through that way.
Tip two:
Make sure to do each side individually, that way you won't get the colors wrong when you alternate between bead colors.
