Yeah, sorry the pattern says (ktbl, p) repeat for 1 1/2 inches longthen continue in stockinette until it measures 10 inches. So I guess that means purl the next stitch?
What is easier for a beginner to knit with DPN's or 2 circulars?
Yep, just p the next stitch, it'll turn out as twisted ribbing. And what's easier is personal prefrence. 2 circs may, but maybe dpns, or even magic loop.
