@grod you do it like a normal candy stripe but after you finish all the colors, you take the last color you ended on and you back the other way, if that sounds confusing you can look up a tutorial! search “zigzag string bracelet pattern tutorial” and you should be able to find one!
@phoebe-07 there might be a tutorial on youtube somewhere! try searching "zigzag friendship bracelet". but you just do the rows of forward knots, and then the rows of backwards knots. you just have to make sure not to leave space between the rows, even though the pattern has space in it. hopefully that makes sense!
