Double Union is a space for your projects

Things women do in this space include sewing, programming, electronics, woodworking, fiber arts of all kinds, and zine making.

Fast internet, shared tools, a carefully curated library of books and zines, and discussion spaces make this a great space for working on your projects, learning skills, and meeting new friends.

Double Union is a supportive community for feminist activism. We are intersectional feminists, women-centered, and queer and trans-inclusive.
