This technique can be used for hat cuffs, sleeve cuffs, and neckbands - any time you're working from a cast-on row in-the-round.
The yarn I used for demonstration is from Marigold Fibers.

And the hat pattern I'm using (but modifying with this cuff) is Branta:

My nail polish is Gelish "Black Cherry Berry".
