Need Recommendations

Can anyone recommend a good, non-pilling, soft, 100% cotton yarn for knitting a sweater (Arwen)?

In other news, I'm sure Kathy Zimmerman would be very pleased to know that I've finished my first sleeve of the Bazic by following her very simple, straight forward directions and it looks really nice. Just like it should in fact. Nice, yes? Don't mess with Kathy, she's a Badass designer. I, on the other hand, am not.
