It is a pattern from The Cabin Countess. The way the instructions read there is a turn, but no wrap. It reads "Slip the first stitch and knit to 1 before the end. Turn, slip the first stitch, purl to 1 before the end. Turn, slip the first stitch, knit to 2 before the end. Turn, slip the first stitch, purl to 2 before the end. Continue in this manner until you have 9 stitches on each side, ending with the purl row." I am doing this on 30 stitches, and I am not quite sure how it gets to 9 stitches on each side. Everything I have seen on line tells me it should be 1/2 of the total stitches which would be 15. I like the video you have shared. I will give it a practice run. Thank you!
