The array of sticky notes full of positive, inclusive, hopeful messages written by passerby at 16th and Mission streets will be taken down and preserved on Friday evening, artists who organized the public participatory art installation say.

Though they originally planned to remove the notes the same day, the “Dumbledore’s Army Guerillas” have kept the wall open to messages all week. To protect the notes from predicted rains on Saturday, they will collect them on Friday evening, but not without a community gathering to end the nearly week-long exchange of supportive thoughts.

At 7 p.m., the organizers plan an evening of community-building, music, and conversation about what to do next at the 16h St. BART plaza.

“Thank you to everyone who has stopped by to write a note, drop off extra pens/markers, picked up trash. Keep it up. We love you,” they wrote on Facebook.
