When the San Jose Museum of Quilts & Textiles opened in 1977, it was the first of its kind: the only museum in the nation dedicated to textiles as an art form. Now it’s the last one standing in Northern California after its San Francisco counterpart shuttered amid a funding crisis about a year ago. San Jose’s quilt museum, a sunny gallery and gift-shop space in the SoFA district, says it will close its doors unless donors come through with $80,000 before the end of March. (About $50,000 had been raised so far.)
