I’m knitting the saga sweater by petiteknit. I’m currently trying to make the gauge swatch and struggling.
In the pattern it says that the cable chart is read from right to left on the rs and from left to right on the ws. There’s an arrow that points to the bottom right corner and says start- so I gathered that I start on the rs but then on the second row there are cables that need to be done. Am I supposed to do the cables in the wrong side of the work??
Pls help me
