This yarn is starting to pool a bit as the foot takes shape. This is not a self striping yarn- the patterns are coming from a very shallow angle of stacked color. The pure red sections of the yarn are only about 7 inches long. I don't mind the pooling at this point- but I imagine that when I get to the heel and the leg this striped effect will be broken up into a homogeneous mix. I think if I was doing a sock pattern which had a knit texture- I might be annoyed by the dominant pooling effect.
