I’m tall, and the cuffs of my gloves never quite overlap enough with my sleeves to keep out drafts. These wrist warmers (I think of wrist warmers and scarves as caulk for people) fill the gap nicely. The ribbed middle hugs your wrist, the stockinette end flares over your hand (and fits over your gloves).

If you’d rather not sew, use a provisional cast on and knit in the stitches 5 rows after the turning row. And if you’re opposed to picots, work a purl turning row instead.
