Emerson's desk is just full of knitted cozies. Nothing says "knitter" like a coffee mug cozy.
The sweater vest Emerson made
The ever so popular gun cozies. I wish I had a better picture of these.
Money sock FTW!
Olive's pretty lace cardi.
Chuck's pink cardi.
Ned's scarf. This looks a lot like those Harry Potter scarves.
OK, so the mittens are crochet. Still cool though.
A lot of these seem pretty basic, especially Emerson's cozies. I'm sure there are some patterns online for most of these items, or at least some similar patterns.
I've also noticed that Chuck wears a lot of cardigans on the show, but couldn't get a decent cap of those.
Anyhoo, I hope this post was useful to someone.
