Sorry the picture and posing and camera quality is all so awful, but I just re-found this scarf while cleaning my room. It is the biggest project I have actually ever completed, and I am very proud of it. I plan on editing in the source of the pattern later, but it is the first thing to come up when you google “binary scarf” and the pattern is great.
The numbers actually spell out things in binary code, but the message is a secret.
