Sandals, embroidery thread (mine were by DMC), scissors, gold thread and tweeters
Start by making your tassels, take your embroidery thread and wrap it around two fingers about 10-12 times leaving a small gap between your fingers. Gently remove the coil of thread from you fingers. Take a small length of gold thread and loop it through the coil and tie a secure knot. Take a second length of thread and tie it around the outside of the coil pulling it into your tassel shape. Once you have tied that securely you can cut the loops at the bottom of your tassel.
Trim off the ends of the tassel until it looks even and is all the same length. Repeat these steps until you have made enough tassels for both your sandals. Take your tweezers and poke them through the strap of the sandal and pull one length of the tassel tie back through the strap. Secure it in place with a few knots. Turn over the strap and trim away any excess ends, you could add a touch of glue to the knots for security too.
