Step 8: Add the sandal thongs
Down the middle of each sandal on the inside, you'll have the two thicker ropes. To add a sandal thong, the trick is to separate the twine in that area enough to expose one of the thicker ropes, and then thread the rope for the thong through the sandal making sure it wraps around this rope. It sounds more complicated than it really is. In order to open the weaving far enough to do this, stick your scissors through the sandal and open them, using the leverage top pry open the weaving.
You'll now have a left and a right sandal.
The thong rope itself can either be the sisal rope or the jute for this. I used a double length of the Jute twine I wove the sandal out of to make the thongs.
Each thong string should be about six feet long so you can cut off the excess once you wear the sandal. Thread the thong strings through the loops in the side and heel of the sandals.
