where do you buy your yarn?

[~*max*~]

I have recently begun crocheting again, and I'm wondering where would be a good place to purchase my yarn? Right now I am just working on scarves & prayer shawls, so I'm using some nice soft acrylics (chenille & the like), but I would love to find some nice quality natural fibers for future projects. Any websites, stores & advice would be appreciated.

TIA. :

I like Knit Picks. They have a lot of yarns to choose from, and the customer service is very good. I like wool, so I'm not sure about what's good in acrylic.

ETA: I noticed Michaels was having a great deal on yarn right now.
