You will need at least 50 socks with holes, unpaired socks, or otherwise no longer useful socks. My wreath used 180. If you can't find these for free from your friends, family, and coworkers check out http://usedsocksworld.com/category/new.htm
. You will also need a needle, thread, thimble, and something long and thin to push the socks into each other like a drumstick.
