My favorite fabric store in San Francisco, Britex Fabrics (146 Geary Street, SF, CA. 94108) is having their huge fall sale where all fabrics, notions, and remnants are 30% off. I went last year to get fabric and supplies to make doggie Halloween costumes, and ended up getting a bunch of other great things for my craft stash. Find out more about the sale on the Britex blog.
