@molnar33 it depends what kind of ends or sides you want. It's a lot to explain but there's a good video on pattern #8489 on how to start. If you'd rather have solid color edges, the video by @pattncraft on #26204 shows another really cool technique. Hope that helps!
I have a question. To do the shaped bracelets, is the outline where you start your knots? So in this ex would I do forward knots w the black,white,black,blue,black,white,black,white and the same thing for the left side going backward then start the pattern?
