If you have never knit a Möbius cast on, prepare to have your mind blown. The cast on itself is similar to a provisional cast on worked around a piece of waste yarn. However, both the cast on and held stitches are worked in the very first round of knitting instead of waiting until later.
The result is a tubular shape that's rather mysterious to knitters. A Möbius has only one side, the right side, and only one edge, the bound off edge. Think of it as a three dimensional figure eight.
