For the purposes of this exercise, the Pink cord is the left-hand (LH) cord of your pendant, and the Off-white cord is the right-hand (RH) cord of your pendant.
Take the end of the LH cord and wrap it around the RH cord, looping it back to the left as pictured.
Slide the end of the RH cord over to lie alongside the main section of the pink LH cord.
Wrap the end of the pink LH cord around the two cords, looping it towards the left and at least 2-3 times.
Now poke the end of the LH pink cord underneath those loops and back out the right-hand end. Pull tight.
Voila! You have your first sliding knot!
If necessary, pull some more of the RH ( off-white) cord thru to the left, so you have enough to make another sliding knot.
Wrap the end of the RH cord around the LH cord, as shown.
Wrap that end around the two cords, wrapping towards the right at least 2-3 times.
As before, poke the end of the RH cord back towards the left and under the loops. Pull tight, and you're done! Trim ends if desired.
