This can be painted over the summer! Buy a canvas from your local crafting store and just replace the ZTA symbols with our own. AXΩ, a lyre, carnations, "Real Strong Women," Est. 1885, Zeta Eta, cute sisterhood quotes, the possibilities are endless! From Tumblr.
I covered a thick canvas with fabric and glued the buttons on with hot glue. You could sew them, but it would take much longer. I’ve also seen this hung with a ribbon, and I’ve seen them where each letter is on a different canvas and they’re hung together.
