WEBS is the best yarn store ever, full-stop. It's in Northampton, which is about 2 hours from Boston. The best way to handle that is to drive out early-ish in the morning, go yarn shopping but don't buy anything, go to lunch at one of the really good brew pubs in town, check out the rest of Northampton's sparkling downtown, go back to WEBS, try not to spend your entire life savings and then head home.

It's worth the trek, I promise.
