as a book in flesh and blood:
Wendy D. Johnson
Toe up socks for everybody
Socks from the toe up
I have the secondly named one of those and I am very happy with it. It has an introduction part that tells all the technique. Then it has 3 base models with the 3 heel-types and (I think) differnet toe tips.
It also has a bunch of actual patterns with lace, cable and such. But the 3 basics get you right down.
I got the book for my birthday and made the sock with roses and hearts. I will make more of those socks. And I have just whipped up baby socks toe up with a different heel type for practice
I do not have any other toe-up books, but I am happy with the instructions I get there.
