My DH had a meeting during May in San Francisco - so of course, I needed to join him. One day I ventured out and found Art Fibers.
This place is physically unassuming but the yarns are truly spectacular! I did come home with a few balls - but came away with lots of ideas. This is a place where they encourage all sorts of experimentation with fibers. (For the curious I bought two balls of Sage- an alpaca/merino mix - for a hat and a ball of Misti (I don't see it on the website but it is a lace weight silk/mohair mix) in rose for a scarf. I needed to pet the Kyoto - it was gorgeous. They have comfortable chairs by the front window and samples for people to try out so they can swatch and feel the fabric.
