My suggestion would be to get some cotton and knit yourself a dish cloth or wash cloth. It's small and you can practice your stitches knowing that it's something you can use no matter how it turns out. Trying to make a scarf when you're first learning is not such a good idea because scarves take forever to make. At least a dish cloth is small and you can see your results quickly.
Just my humble opinion!!
