New Socks on 4 Needles

I have been dying to get a chance to cast on with this yarn, I bought it at Dutchess County Sheep and Wool, it is Scandinavian sock yarn, it has an oily feel to it and get softer every time you wash it. I bought yards and yards in natural and gray. I found this very simple but sort of fancy sock design, it is the first time I am using the picot edging...verrry fancy! Does this mean i won't knit the heel in the last sock that I was working on? You can never have enough socks cast on, that's what I think.
