Bamboo scarf

I bought some bamboo yarn while in Missouri this summer. I started knitting it while on the road trip home. I've been working on it off and on during late night movies or tv shows. Today I worked on it while my husband drove us around for errands. I just finished one skein. I was smart enough to buy 2 skeins. I am debating on whether or not to make a matching hat. I am sure that I have enough, because the scarf it already pretty long. Or maybe I should just make a super long scarf. What do you think? I am using size US 9 needles that I also bought in Missouri. They look like glass needles with a blue ribbon twist in side, but they are plastic.
