awesome pattern!! i made mine in a single evening, it's a very simple pattern once you get past the first triangle. make sure not to lose count of the rows though, and always double check if you think you might've miscounted while knotting. My photo should be up soon, i just submitted it.
Yes, this is supposed to be braided. I got inspired to make this pattern by @mjlgvw patterns #74845 and #74846 and wanted to transform these into a braid.
Like @dojac says you start by connecting all the strings on top. Then you knot the individual strands until they have your desired length. To get the zig-zag shape of the strands you always knot 12 candystripe rows into one direction and then in the other direction. Only the first and the last part is shorter so the individual strands line up perfectly. I recommend first knotting the individual strands and then braiding them. To end the bracelet once you have the desired length you connect all the individual strings again.
