Nothing says you care like a handmade gift come holiday time, but if what if you were born with two left thumbs and zero creative skills? San Francisco Center for the Book is here to spare you from another year of presenting your friends and family with Target gift cards. The Holiday Book Arts & Crafts is a one-day-only show featuring dozens of talented artists and crafters, but a touch more intimate than the sprawling craft shows that tend to propagate this time of year. Organizers promise music, refreshments, door prizes and something called merriment.
