My oldest (8 yr) picked his favorite color for his Kool-aid socks. We used Lemon-Lime mix with Berry Blue, Lemon-Lime with Orange (to get the army green color), and Lemon-Lime with Lemonade. I think the yarn turned out gorgeous! I also dyed longer sections hoping that it will stripe up a bit thicker than my first attempt (which I also like).

SIZING:
I cast on 40 stitches with #6 US needles - this was sized for a women's small, but this actually fits a boys size 3.5 feet perfectly. My middle kid has a size 13 childs and I cast on 36 with #6 - same thing. Perfect fit with some room to grow.
Completely unrelated to knitting: Living in the woods and near a lake means that I also live with . . . spiders. I don't know anyone who really LOVES spiders, but I, for one, take no joy from them. I am an arachnophobe. And I don't mean - "Oh, ick. A spider." I actually have two responses to the sight of spiders - 1. a flight of terror 2. loss of all control - ending up with me in a heap on the floor, sometimes whimpering and shivering (I think with shock). Often times, my response is a combination of both.
My garage sits under a canopy of spider homes in the trees above. When I open the garage door, I stand far back and wait for the door to come to a complete stop - (spiders may drop from the garage door onto my head). Next, I make a terrifying dash to my door, sometimes shrieking, trying not to focus on anything in case spiders are crawling on the car. When I manage to get in, I close my eyes and wait to calm down. I'm certain that my doom will be a car crash involving me and a spider that has hitched a ride inside my car.
When my husband asked me to marry him, I had two prenuptial stipulations - I will never be tickled (hate being tickled) and don't ever . . . EVER throw, pretend to throw, or put real, dead or plastic spiders in any location to try and scare me or I'll file for immediate divorce. He has not broken this rule yet and, in fact, will diligently dispose of them quickly and quietly without so much as a rolling of his eyes.
As a back-up plan, I also have a generous neighbor who is on-call for emergency spider disposal at any time of day (she's not so generous in the middle of the night). In return, I judiciously dispose of toads in her garden. Don't worry, I only remove them to my own garden (they eat spiders). I'm unconcerned with beetles, bees . . . heck, even snakes. But . . . (shiver) spiders... And did you know that lake/woods are also home of the insanely huge and very fast "Wolf Spider" and the even bigger "Fishing Spider" (which sometimes takes a break from fishing to come inside my house). I'd post a picture, but I actually have a nasty physical response to photos as well. If you'd like to get me to stop reading your blog, you can post a big picture of a Wolf Spider - any spider - and I'll never return again.
