Although the heat of summer is still baking most of the country, San Francisco is an exception. In San Francisco, you can wear a sweater almost any day of the year. Still, winter is coming and like all of nature, we start preparing for cold weather. Chris bought some yarn at Atelier Yarns on Divisidero Street and has started to knit a scarf of rich harmonizing colors. See above. Some lucky person will be looking very dapper this December.
