Start by cutting leather into strips approx. 1.5 inch wide by 5 inches long. Once you have your strips, fringe cut the ends leaving about 1.5 inch-2 inch in the center uncut.
Now that pieces are all fringe cut, start at one side and roll up the leather.
Fold the leather over the strap of the sandal and hold in place. Use pliers to create a half loop in one end of the wire and wrap it around the leather up near the strap.
Then use the pliers to help wrap the wire the rest of the way around the tassel to create a secure hold.
Repeat with the other two tassels, and then the other sandal. Once you have all the tassels on your sandals, use your scissors to even them up a bit.
