Swatches? For wimps

I may have started and ripped out this scarf twice, but third time's the charm, right? I think I have the right width now, and I've settled on 1:1 ribbing because it looks more like stockingette stitch but doesn't curl. My first scarf ever is mostly done now, I'm just weaving in 500 billion ends because it's striped. I need to figure out how to carry the colors along the side or something to avoid having to weave in 38 ends again.
