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 in-progress fair isle hat is Coronal, using Quince & Co. Chickadee yarn.
The needles I use for demonstration are Knitter’s Pride Zing, and Knitter’s Pride Royale.
My needle gauge ring is by Malojos.
My nail polish is Gelish “Black Cherry Berry”.
