The closest shop to you is probably the Knitting Nook at Rufe Snow & Loop 820. It's a pretty nice shop, good selection, helpful, friendly staff. Also Simpatico at Brown Tr. and Bedford Road, though the selection there is not as large. Very nice people, though.
In Fort Worth I shop at Jennings Street Yarns. The owners are very nice and helpful, and they have lots of beautiful (if pricey) yarn. And once in a while I make the pilgrimmage to The Woolie Ewe in Plano. It's a good thing I don't live closer to this shop -- I'd be broke all the time.
