Double Union

Double Union is a women’s members-only space in San Francisco for crafts-people. Projects developed at Double Union include sewing, programming, electronics, woodworking, fiber arts and zine making. The facilities provide fast internet, shared tools, a carefully curated library of books and zines, and discussion spaces. Double Union describes itself as a supportive community for feminist activism that supports intersectional feminists and queer and trans-inclusive.

The facility is located in San Francisco’s Potrero Hill neighborhood.

Other than during events open to the public, Double Union visitors must be the invited guest of a member.

Open house events are open to the general public. Visitors do not need an invitation from a member to attend an open house and may be any gender or age. Members join through an application and voting process, which is periodic.

The spark that started Double Union was AdaCamp San Francisco, a feminist conference that took place in June of 2013. At that event, a group of women came together to talk about starting feminist makerspaces where women’s needs are prioritized. Among them was Leigh Honeywell, who had just co-founded Seattle Attic, a feminist makerspace in Seattle, who shared her experience and tips for starting a makerspace. Several women, including Double Union co-founders Amelia Greenhall, Valerie Aurora, and Liz Henry, were inspired to start a similar space in San Francisco. They decided to create a space with the primary mission of being a comfortable and welcoming place for women to work on their projects.
