Here are the clues:
1) It's a popular (possibly even viral) knit.
2) At least one of you has knit one.
3) It's an incredibly addictive pattern, and I've done nothing but knit this since I cast on last night. I had to rip back completely once, because I made a mistake and it bothered me, and I had to do some significant tinking twice. The first time was because I was knitting in bed without my glasses on before I got coffee. This was a big mistake. The second time I got distracted by the show I've been watching (Dead Like Me) and couldn't figure out where I dropped a stitch.
I'm also curious if anyone can identify the yarn. I promise there will be better shots of this. It's working up rather quickly, but I also think it will end up being a bigger knit than I expect. For indoor flash photography, the color's actually fairly true. In person, in daylight, the color is a bit more crushed grape, and it has almost a velvety quality.
Now to sneak in a bit more knitting on the couch before I collapse. I should by all rights do that now, but I'm not quite ready to call it a night yet.
