This is a very basic slipper sock, made toe up, using 2 strands of 8 ply and on a 24 peg round loom.
We’ll start with a heel (this will be the toe).
Complete a heel using this video http://www.youtube.com/watch?v=5e3J0fuYz-U Do it over 12 pegs, and using ewrap (to make it stretchy enough).
When complete, lift 12 stitches from the half heel, and lift up on the pegs that are empty. Like this:
Ewrap 20 rows (or to 1 inch less than foot length if you put it on)
Complete another heel on the same 12 pegs.
Ewrap 5 rows (any length you want!)
Top of sock (I use ribbing to keep it on, but use anything you like)
k1p1 for 5 rows
I love the Super stretchy bind off http://www.youtube.com/watch?v=myvq5LBD6ic but use whatever bind off works for you.
