In fall and winter arm warmers, leg warmers and various shawls are very popular as they help to get warm. You can easily make a pair of arm warmers of knee socks, you’ll need: knee socks, needle and thread, scissors. Take a pair of knee high knit socks and cut the foot section off of them. Remove the sleeve and turn it inside-out. Stitch the raw edges of the hole down. To do this just take a full needle-full of the edge near the hole and just a few strings from the fabric outside of that area- it will hold just fine. Trim your extra threads, turn the sleeves back around and you are done!
