I've made several scarves out of the fun fur! I knit the entire thing, and did 20 stitches on size 10 needles. I used exactly 2 skeins of yarn (no clue how many rows that was). I liked the way it turned out, but when you get several rows on, you will see if you think it's too thick or thin for your tastes. Also, as you knit, you'll see the length as you go, and just keep knitting until it's where you want it to be! =) At least when I did my scarves, the first one I started and restarted a few times to get hte width I liked! I would say for the scarf, just do what you like!
