@Traveler You would make the first six strings one color and the last six strings a different color. You would also need to change row 7 to fb knots, row 19 to bf knots, row 31 to fb knots, row 43 to bf knots, and so on.
@Dis_abled I made this bracelet as kind of an experiment, if you ignore the gaps and tie each row right up next to the previous row it makes kind of a 3d triangle pattern. I posted a photo of a little swatch I made if you want to look at it.
