Not My Best Hat...

About a year ago, I started knitting a toque. I forgot about it for a while, but then I had some time to just finish it yesterday.  I've knitted some hats before, and they turned out pretty well except that they were kind of pointy at the top. I decided to go with a pattern that looked particularly un-pointy... at the top.

It's just so lumpy everywhere else!!

I think the yarn is to blame. I used the cheapest worsted-weight acrylic I could find. I'm hoping that once it stretches out and relaxes a bit, it won't be so lumpy. 

Any tips, knitters?
