The pronoun ribbons were first created for Foolscap in 2015. Electric Keet designed the ribbons and the project was managed by Jason Wodicka. Electric and Jason are both organizers of Foolscap.
Tabletop Gaymers — a nonprofit organization whose mission is championing the visibility and inclusion of the LGBTQIA+ community through tabletop gaming — adopted the use of the ribbons at Gen Con in 2018 and manages the website as of 2021.
Who else has done this?
This isn’t some unique idea. There are other sets of pronoun ribbons around, and it’s great that there are lots of people looking at ways to support people being identified correctly. If the ribbons we designed aren’t right for you, we hope they inspire you to improve upon them.
The Pronoun Ribbons Project (defunct) had they/them, she/her, and he/him pronoun sets in silver on black, and “What are your pronouns?” and “Ask me about my pronouns!” in black on white.
Arisia 2015 had a large set of pronoun options in black on hot pink, including “No pronouns, just my name,” they/them/theirs, she/her/hers, xe/xem/xyrs, ze/zir/zirs, ze/hir/hirs, he/him/his and __/__/__.
In a different medium, Non-Newtonian Gender Fluid has a set of name-tag style buttons with printed pronouns.
