Yarn troubles

[Skyrimir]

I'm not sure if this is the right place to post this.

I found two balls of this yarn at hobby lobby and fell in love with the colors. I want to make a scarf, my only problem is that I can't decide what stitch to use. I have tried seed stitch and garter stitch and they both look messy and uneven. I haven't knitted with this kind of yarn before. Does anyone know what kind of stitch would look good with this yarn? I really love the colors and would like to start making it into a scarf soon.
