I’m knitting my first cardigan. I’ve gone for a slip (purlwise) stitch edge and I’m working the right front. I just want to make the nice edge on the side of the cardigan with the buttons, not the seam side. But I’ve noticed that if I don’t slip the stitch while working the seam side, the edge isn’t as nice on the button-hole side. I hope that makes sense. In other words, do I have to slip the stitch on WS and RS too, if I just want the selvedge on one side?
