Center Pull Ball of Yarn

I found this cool site - KnittingHelp.com.  So obvious, why didn't I think of typing this into google earlier?  It's a great site because it has videos!  I've tried to make some videos of me knitting, but I keep making knitting mistakes whenever I'm taping.  Anyway, KnittingHelp.com has videos of basic knitting techniques as well as more advanced techniques like initersia - something I gotta try one day.

The most useful skill, I think, is to create a center pull ball of yarn.  Sure the yarn you get from 

the store is already center pulled but it's a pretty big and loose ball.  Somehow, I usually manage to create a tangled mess when I try to knit directly from an untouched, straight from the store, ball of yarn.  Rewinding the yarn into a small, snuggly wound ball help minimize tangles.  A bonus in all of this is that you can buy more yarn since the yarn balls are so much smaller!
