Oh, I see! Should I erase my post? Thanks Kelly, for letting me know about it, though...I have so many places to check I don't get to it right away, and thank you, Yvonne, for the wonderful scarf pattern!
No, not a RT in every K stitch. The twists are only done on the second and third rows of the main body pattern, on the two knit stitches as they appear on those two rows. The other two rows are K2, P2 with the knit selvedge stitches.
