It appears that a lot of us like the Hitchhiker scarf by Martina Behm. Ravelry shows more than 11,000 Hitchhiker scarves, which is perfectly understandable. Even though the pattern is relatively simple, watching the color changes keeps the knitting interesting (I admit that sometimes it does not take much to keep me entertained). I first saw a Hitchhiker in person at my knitting guild, and pretty soon, lots of Hitchhikers showed up at guild show-and-share time.
Mine is made from Noro Taiyo Sock Yarn, color 27. Content is 50% cotton, 17% wool, 17% nylon, and 16% silk. It was kind of scratchy to knit with, but once washed and dressed, it is comfortable to wear. I got 37 points out of the 460 yards. Knit on 3.25mm needles.
This was a fun travel project while I was visiting Richmond, Virginia, earlier this year.
