Truly, it doesn’t.
I have this pair of socks that I started possibly in May or perhaps April. The fact that I can’t remember exactly when should be a sign to me that I ought to finish that pair before starting ANYTHING else.
The Chickengoddess lent me an Interweave sock book (25 Timeless Sock Designs, or something like that), mostly because it has a great explanation on how to do a kitchener stitch, and I got to looking through it. And then I got to looking at my sock yarn stash (which is small and the only stash I have). And then I was madly rifling through my needles, all the while grumbling at my husband that I was certain I had a set of size 2 needles, after which I discovered that another pattern called for size 1 needles, and lo and behold I have an extra 4 of those I’m not using, so I knit the hat that was on the bamboo needles onto the metal needles (which are much longer and will therefore not drop stitches quite so easily), and then I cast on a new pair of socks.
Mind you, I also have a pair of Jaywalker socks that I am working on, too.
But these are pink! And involve lace! Pink!
My excuse was that I couldn’t find the pattern for the Jaywalker socks, and therefore couldn’t work on the toe, but the real reason is that I’m totally all over the place and am not happy unless I have more projects cast on than I have actually completed. I imagine this is not unique to me, and while this offers me some consolation, the Very First Pair of Socks remain unfinished, because they are 2×2 rib and I have moved on to more complicated knitting (I did try one on and they are very, very cushy).
