So I had to join the sock bun hair hype and try it out for myself and I have used it at least once a week since. If you have not already worked it out I am a lazy styler. Maybe I am more time poor than lazy but I am trying.
Take a clean sock. I used the freebies I got from the Aeroplane that I knew I was saving for something (I have around 50 toothbrushes too).
Cut the top off the toe and roll it to make a thick rounded band like this. Then roll your hair into the band. For more photos of my head and the technique check out my Sock bun tutorial on Craftbits.com
