I wanted to make some reversible slipper socks that were also really warm so I decided to try making these socks using double knitting. It was quite challenging to figure out parts of the sock using double knitting, especially the toe at the very beginning, so I recommend tackling this pattern only if you have sock experience and double knitting experience. This could be a fun pattern to try as your first double knitting project, but it could be a bit frustrating, so beware! There’s a great photo tutorial on double knitting available here. I tried my best to explain my process as a helpful guide.
