only 1 sock required to curl hair! Must try this! (Pinner comment - With the extra sock, I cut the band off to use as my pony tail holder. It’s soft and doesn’t leave the dent that some were worried about. Then I used the toe part, cut about 6 inches and used that to cover my bun so my hair wouldn’t fall out! Worked like a charm! My bun cover was still in place this morning!) - gotta try this!
