measure your feet

I have knitted silly socks that are just a little too small for me, and I'd rather they be worn properly. I hate to ruin a surprise, but they are in green and blue shades. I reserve the right to make myself another pair. :)

Foot length: not as stretchy as anticipated, about 7.75"
Circumference at arch: very stretchy, 5" to 9" would work fine

First Cinderella to call them gets them, plus maybe some other stuff if I find appropriate accompaniment.
