I realize this is an older video, but if anyone can help me with this problem, I would really appreciate it. I am making these type of bracelets to sell and I know how to make them, but I cannot figure out how to get them the correct size. Let's say for example I want the bracelet opening to adjust between the sizes of 6 inches to 10 inches. How do I make this possible. Am I supposed to place the knots a certain distance apart, am I suppose to have a certain amount of double cord between the knots? I just can't figure this out :( Exact measurements are important to me so I can be consistent in my size offerings on my website.
