There were also a couple of other topics in the comments, which I decided to revisit. By "not boring" I meant I didn't want it to be boring-looking. I'm actually perfectly happy knitting boring stuff because it allows me to pay attention to a movie, and I have a very long Netflix queue. (And Ravelry queue, for that matter, good thing they're complementary.)
Patterns like Monkey and Jaywalker are probably so popular for just this reason - they're relatively easy to knit, but produce nice non-boring socks. My current one is a modified version of the Gentleman's Shooting Stockings from Knitting Vintage Socks.
It's a simple textured pattern, but it adds some interest to this yarn. Although if I had known originally that the yarn was stripey, I might have done something a little less fancy. In any case, I think they're turning out well.
The closeup of the stitch pattern is a little blurry, sadly winter light isn't great for taking photos.
And thanks to Cindiluhu and Chris for validating my sock-knitterness. The truth is that I want to knit other things. I'm not planning on stopping the sock knitting - not even close! But I do want to knit a few things that aren't socks. And the actual process of knitting a sock vs. a sweater doesn't make that much of a difference to me. The problem is more that when I go to cast on a new project I don't grab the yarn for that sweater I want to knit, I grab more sock yarn. (There's a lot of it, it's in exciting colors, I don't have to swatch!) But I *do* want a Ribby Cardi and a new scarf, so I should really get to knitting them.
As for sock leftovers... I have tons. This problem is compounded by the fact that I have small feet. I was actually thinking I should find someone with a loom and get them to weave me a scarf with black yarn for the warp and stripes of all my crazy sock yarn leftovers. I think it would be cool! Maybe in exchange for a pair of socks... ;)
