In honor of Women’s History Month, this collage workshop invites participants to explore collage as a practice rooted in storytelling, care, and reclamation. Together, we will look at how women and femmes have historically used cutting, layering, assemblage, and repair as forms of documentation and self expression, often working outside traditional art spaces and definitions of what is understood to be "fine art.” Participants will create collages using photographs, found papers, textiles, and personal ephemera, reflecting on lineage, memory, and the quiet labor of the women that shapes our lives. No prior collage experience is necessary. This workshop is designed as a welcoming, reflective space where participants are encouraged to work intuitively, honor their own histories, and engage with material in a tactile, intentional way. All are welcome. Registration is required.
