Here is a free crochet pattern for a pair of simple flared wrist warmers. They are quick and easy to crochet up and have nice flare to them. I used Red Heart Comfort yarn, but due to the nature of the pattern, you can use any kind of yarn that you like.
The crochet pattern is given for a pair of wrist warmers, but by increasing the beginning chains, you can also crochet a matching pair of ankle warmers. To customize the circumference, simply increase or decrease the beginning chains in multiples of 6. You can also increase the length by doing more repeats of round 2.
