@odana1811@nada_art_s You don't have to do anything after, just be aware of knot tension during, and every few rows when you readjust your pins/tape, pull the ends of the newly-worked section taut and wiggle. What you're looking to do is loosen the knots a tiny bit and straighten the bracelet. When you stop wiggling and pulling the knots will go tight again in the new shape.
It's a quick and simple procedure that takes only a few seconds.
You can also try pulling the base string tight downward as you knot, which will pull the knot colour to the correct spot.
I'd make a video, but I don't have a way to film myself.
@nada_art_s Having most of the knots in the same direction often makes the bracelets curl a bit. Even after doing more than 500 bracelets I still tend to avoid these kinds of patterns because it's harder to get a straight and flat bracelet as a result. I know there has been some forum posts where people discuss methods to straigthen the bracelet after, like using an ironing board or putting them for a while under a heavy book.
