Step 3: The knot

Picture of the knot

I didn't have a thin chain but I had some ladder ribbon I use to make necklaces, I did a very basic crochet/macrame chain stitch where you make a loop in the string, pass the string back through the loop to form another loop and pull the 1st loop snug and repeat as needed. I left some of the ribbon unknotted and tied the 2 ends together.
