I got a sock loom today! It is a rectangle of metal pegs that are closer together. It has a sliding short side of pegs to help vary in sizes. It is pretty much a tighter, and adjustable round knitting loom. It is very easy to make socks on this type of loom.
Please check out some video tutorials on how to knit socks like this. I doubt instructions I write will do you much good. ;)
More updates to this post soon, so check back in a bit! :)
