I wanted to use the wavy welt pattern to make a cowl. I also wanted to have the welts make a chevron. The stitch-pattern itself is reversible, but adding increases in the middle and decreases at the edges complicated the reversibility when it came time to use the pattern as the basis for a Möbius cowl. I finally figured it out. I hope.
