I did adapt it by adding a full twist rather than forming a Moebius strip as written. I also shortened it so it fits comfortably around the neck rather than shoulders.
The piece is knit in the round, as a tube, and then grafted together after the twist. Fun, fun, fun! I came across The Purl Bee’s video tutorial for Kitchener stitch, which I think is helpful if you haven’t grafted before, or need a refresher before diving in.
I hope you enjoy wearing it, Jane! And a very happy holiday to all!
