I made two Irish Hiking scarves for Christmas gifts. They are both knit with two skeins of Patons Shetland Chunky
in Oxford Grey and Sage Green. I cast on 30sts and only did two cables because of the heavier yarn. I didn't measure them after blocking, but they are at least 6' long and maybe 6" wide. They are definitely long enough to wear in several different styles. The grey one was started December 1st and finished the 4th, Ravelry
The green one was started December 5th and finished the 9th, Ravelry details here.
