Super easy since they are socks without the fussy bits like heels and toes. These are just some nice soft cotton blend that I have tried to make other socks with, but this yard did not want to be normal socks, so now it will be special socks.
Just cast on your stitches to fit your ankle, knit until you would start the heel, then just cast off half the stitches. On the next round cast them back on so now you have your tube again, then just knit until the foot part is as long as you like it. Now your heels and toes are out so no slipping on mats, but you can keep your feet warm and stylish!
