And I did.
But then one of my readers mentioned that she had seen this same collar called a "Miss Marple Scarf." So after a bit of hunting, I found this great free pattern off ravelry. Armed with an official pattern this time, I had to make another one!
I found a nice, medium blue yarn with tiny sequins scattered throughout. The pattern directions were very easy to follow, utilizing mostly knit stitches except for the short ribbed sections. If I were to make yet another one, I'd knit it just a bit longer in length and narrower in width. But as it stands, it's very cozy.
