I've been meaning to mention that Yarn Thrower Laura has written up the pattern for a really cute pair of (seamless!) baby booties, and has posted it on her blog. She's even included two ways to work them: top down and bottom up.
Remember the sock with the gaping hole in the bottom? I decided that instead of darning it, I would just re-knit, because it wasn't that far from the toe, and because I wasn't sure how comfortable a darn would be under the ball of the foot, and most of all because I enjoy the process of knitting and do not particularly enjoy the process of darning.
I "always" save the leftover bits of yarn when I've finished a pair of socks, just so I can use them for mending later. Always must be relative, because I couldn't find the leftover bits of this yarn. So I ended up using small amounts of three others.
I think the finished effect is rather festive (you can click on the picture for a close up). Of course, it no longer matches the undamaged sock, but life is too short to worry about things like that. And of course I no longer have mending yarn in those other colors, but Ha! they were all from socks that I gave away, or lost, or something. At any rate, they are all from socks no longer in my possession, and therefore not subject to mending by me.
