[Comments] You may want to do a few decreases before you start ribbing for a tighter fit. Or you can switch to smaller needles for the ribbing. [Mitten instructions] 
Work even down to wrist. Switch to ribbing and work till cuff is desired length. Bind off loosely, so the mitten can be put on easily. Work in end of yarn.
