Last week I finally bit the bullet and ordered some sock yarn, along with various needles, from Knitpicks. I've eagerly awaiting my package, and it came today!
I got 4 skeins of a cotton/wool/elastic yarn called Risata in Cocoa, some double-pointed needles, and a couple circular needles in different sizes for various projects. The yarn is very soft, and is so yummy looking. I might not need all of it for my socks, but I can always make another pair. :o)
There's a method of knitting socks called the Magic Loop that I'm going to try -- it allows you to make two socks on one long circular needle. Hope I can figure it out!
