On Sock Knitting and Project Monogamy

For some reason I can't seem to take flattering pictures of the hansigurumi I've knit recently. They go by super fast, because they're tiny, and they're fun, because it's pretty much just mindless pattern-reading, but I can't seem to take pictures of them that don't look ridiculous.
So for now they will go without, I guess.

But in the meantime, here I was, not really wanting to knit another hansigurumi just yet (next on my list of hansigurumi to-do is the jellyfish) and wishing I just had a little mindless knitting, so I picked up a pair of socks I'd started sometime last spring.

I wasn't sure how much of the yarn I would have when I started them, because the yarn is part of a collection of sock weight yarn I inherited from a friend of a friend (when people find out you're obsessed with knitting and on a college-student budget, they are thrilled to give away stash yarn they haven't touched in ages. I love it because I feel like I'm ridding them of stash they won't touch, and then my friends and I get all sorts of beautiful mystery yarn to play with...I once knit a whole sweater out of mystery yarn...it's one of my favorite sweaters and I know NOTHING about the yarn itself, except that it smells like wool.).

But anyway, the yarn. I have a TON of it, in all different colorways, and almost every colorway has enough yarn for a pair of socks...a few of them more than one pair. So last semester I started on a pair of ribbed socks - knitting from the toe up I knit about an inch past the heel on one, put the sock on waste yarn, and got to just before the heel of the second before getting bored and moving onto something else.

I picked them up again on Friday, desperate for something to knit, and I finished one yesterday at dinner and picked up the stitches for the second one, but I can hear the call of other knits beckoning me.

Historically I'm not terribly project monogamous - I've tended to have several projects going on at once, which is not all that uncommon, but for some reason lately I haven't been doing that...I've been knitting one thing until I finished it, then picking up another project, which I'm finding I quite like...projects finish faster and I never feel torn about what to knit.

So even though I have every valient intention of finishing this sock, I can still daydream about the next thing to cast on.
(I'm giving up on holding out for Thermal since I don't know when the color cards will get here, and after that I'll have to wait AGAIN once I decide on actual yarn. Sad, sad day.)

The first pair of socks I ever knit were for a friend and I knit them one inside the other, using double knitting. It was a fun experience but also exhausting, I think because I couldn't get into the groove of it because I was constantly moving my yarn from the front to the back and vice versa and trying not to get tangled up.
So here's my idea: knit two socks at the same time in the same way, but knit the outer sock purlwise and the inner sock knitwise, so you'd never have to move the yarn. I have no idea if it would work or how it would come out, but wouldn't that be neat?
To avoid mixing up which stitch I was on, I think I'd use two different colorways, and do it twice, so at the end of everything I'd have knit four socks but out of order...it just sounds like fun and I'd really like to try it.
