Well I wasn't brave. I ended up casting on with 2 different colors of yarn for my test socks. Also maybe it's cheating, but I am doing little socks to get the technique down.
Got my k1,p1 rib done and a couple of plain knit rows finished. It's really sort of fun to knit this way. But I admit it might be easier to go with bigger socks.
oneskein is all you need to knit happy
