Another pattern I found thanks to Pinterest! Here's a link to the pattern: Crochet Pattern: Wrist Warmers by Danyel Pink. It's a great pattern and really easy to make.
I used a size I hook with some of the leftover yarn from the Three-Quarter Length Sleeve Shrug I made (worsted weight Red Heart yarn). These only took me a couple hours to stitch up! They'll be great in the winter when my hands are ALWAYS cold. Now I just need to make a few more in other colors! :)
