The store hours are mind boggling - 10 to 4 or something like that. I'm rarely able to shop here because I work during the day, but the few times I've been inside have been great. They have a ton yarns and a nice selection of needles, notions magazines and patterns.
MAKE SURE YOU CALL AHEAD before you go - even if you're planning to go during normal store hours they might randomly be closed.
They've moved to Roslyn, and the store is enormous and beautiful and full of wonderful yarns. The people are so nice and very helpful!
