  Here is one of the most interesting, beautiful yarn stores in the country.  They
have a great selection of yarns from around the world and Montana,  tons of
beads, and all sorts of interesting objects to look at.  There is a cozy corner to sit
and knit (or crochet), make new friends, or chat with old ones.  A feast for the
eyes when you walk in the door!
