Starts off pretty much the same as the Orbit Cowl, but with fewer stitches and a stretchy foundation stitch.

I might keep going long enough for it to be a slouchy leg warmer.

Crocheting a boot cuff in the round means that you have to choose a good circumference at the outset. It also means the rounds wrap horizontally around the leg, instead of having a vertical grain. This give the slouching drape a different look.
