Moebius knitting may be my most favorite knitting playground of all. Once you learn the basics you can play with this form forever without running out of surprises and delights. It is my favorite subject to teach, because my students soon find themselves feeling like happy children. Moebius knitting is probably easier than knitting a garter stitch scarf.
(Note: Do not fall for the knitting myth that twisting the cast-on edge produces a Moebius. This is totally untrue. A real Moebius is nothing short of magical.)
