Used up every last bit. this was knit from end to end, using that mistake rib where you K the RS rows, then K1, P1 rib the wrong side rows. Both sides are great, I am using the ‘right side’ for this cowl/scarflette. Have only about 1 yd left of the yarn. The buttons are just sewn on through both layers, no need for button holes. I also tacked the other side of the front point down so it will not move around underneath.
