uneven shaped stockinette stitch

[corky]

my stockinette stitch looks uneven; not the more typical uneveness between rows. instead each left side of the V is very vertical, and the right side of each V looks very diagonal. I am assuming that the right half of the V is too loose and the left side too tight, but cant figure what I am doing to arrive at that or how to avoid it.

More than likely it's the way the yarn is plied and there is nothing you can do to correct it except change yarns. I think most people just ignore it.
