This yarn was on a time out. ::grumble::
Everything was just peachy until I got up to 38 stitches for the instep and the pooling turned around stabbed me in the back, just like it did the first time I tried this pattern with this yarn. Clearly this yarn wants to be something else. Plain vanilla socks? Or perhaps a lacy scarf? A hat? What say you, dear internet?

Busy yarn calls for a simple stitch pattern. I vote for vanilla.
Maybe you could try the slip stitch pattern I used for my latest socks? It did really well in breaking up pooling.
