Tube scarves and wrist warmers, anyone?

Since I started vacation I've been working on tube scarves as a way to practice working on sets of needles. I guess I'm heading towards being able to knit socks. So I've been working on sets of five needles, setting up the tubes by casting on to four needles and knitting with the fifth. It feels wonky, but I'm slowly getting used to keeping all the needles in order. The tube scarves are supposed to be stretchy, so I've been knitting ribbing.
