I knit this on size 8 wooden circulars, CO between 60-70 stitches, not 100% sure how many, but Link is almost 30 stitches, so at minimum it's 60. I knit the scarf to about 70", and then duplicate stitched the images on. As seen from the previous post, I very heavily modified a couple charts, and I made up the Navi chart. The triforce is everywhere, so I don't feel I owe any one person credit. This was incredibly fun, and I think it turned out really good. My only real complaint is my own guage issue; otherwise, I love it and plan on wearing it all winter!
ETA January 2014: Here are several more iterations I've done of this scarf - I've improved upon the images and each is unique:
And finally, a custom LoZ from a geekster who purchased the original last year!:
