For POPO 2022 I used postcards with buttons and altered them with text. I sent out the full 31 from my list, plus a few to friends, and received 23 list postcards and 4 from friends. My poems were all in shadorma form, taking clues from the front of the card.
There was a nice assortment of both images and poems. But the best part is making the cards themselves, and each day spontaneously composing a poem for each one, and then putting on the stamp and mailing them.
through lost synapses
into narratives that end
you sought 1 special story
and after two years of psychic wandering
the boy said: 3 is my lucky number—what’s yours?
