love my monkey

It's daylight and here's a flash free monkey picture. The colours are really hard to capture because there's so many of them. I've cast on the second sock this morning.

I washed my silk swatch with a little shampoo this morning (it's recommended that you use something like dish soap to get rid of the machine oil but I was too chicken to do it) and chucked it into the dryer. Before washing, I was getting 7.5 sts/inch but after washing, it's 6 sts/inch which is exactly the gauge I was expecting (I'm very lucky when it comes to getting gauge). The swatch is soft and drapey and beautiful. But can you see the problem?

See how the swatch is kinda leaning towards the right. I'm not sure why it's biasing so I don't know how to fix it. Do any of you have suggestions? Is it because I plied the yarn rather than twisting it? The nightie I want to knit is done in the round with distinct vertical elements in the lace so either I need to figure out how to fix the yarn or use something else for this project. Guess I'll be researching this topic rather than knitting Monkey today.
