And we have a winner!

Hooray Carroll! The random number generator picked your comment for the copy of American Sock Knitting. I'll PM you on Ravelry and get your mailing address, and I will post out the book to you as soon as I can.

Thanks to all the commenters - I loved your ideas about sock designs. It's been a while since I actually designed a pair of socks, and I think your comments have sparked some ideas!

Have just noticed that pre-orders have been extended to the 25th of July, so apologies to anyone who comes along after this post!
