Really nice selection of yarns, although they don't stock the quantity of lace and sock-weight yarns that some places do. Nice bright store.The women who helped me hit just the right balance between helping me find stuff and letting me browse on my own. Also they wound a 900-yard skein of laceweight without blinking.
Calling this store the "Walmart of yarn" is bizarre, unless the Walmarts in San Francisco are way nicer than the ones I've been in.
