I've been busy for that 3 days just for make these bracelets. And it is the tutorial how to make the partition. My friend, jeje, ask me to make a tutorial how to make it. So, i can say this post is dedicated for you dear. :)
What you need is the complete bracelets and a string (it is up to you if you want to use a totally different colour with your bracelets. And if you ask how long it is, seriously I don't know :p)
It hard for me if you ask me tell the step so I just can shoot every single step to make you easy to make it.
If you start from right(like the picture) then the next step must be from the left and the next step from right again. Do the same step until it long enough for your bracelet. Good luck!
