I also love making socks because I actually get them finished. Because I sometimes get overwhelmed, I don't enjoy making big projects, like sweaters.
People who don't enjoy making them say that they do not like making things that wear out as fast as a sock does, or things that require hand-washing. I hand wash socks I make because I want them to last longer.
Socks are made "in the round," meaning that they are created on three or four double-pointed needles so that they have no seam. (Circular needles also create items "in the round" but are not used for socks.)
