Knitting a Moebius Scarf

This is the moëbius scarf Fern and I are working on.

To make this, provisionally cast-on 150 or more stitches on a 36" circular needle, size 9-13, with worsted weight yarn. Knit across in your desired pattern (seed stitch, lace pattern, etc.). Now, remove the provisional cast-on and keep knitting your pattern. You will have 300+ stitches on the needle and the circular needle cable will loop around. The first few rows are the hardest because there's no give yet. As you keep going, your piece will get wider and wider. Cast off when you get bored or run out of yarn.
