I love the concept of barter, trading stuff, zine for zine, or other art for zine. Some people have done trading like this, I even got some mushrooms from a subscriber at the Durham Farmers Market, which was really cool.
If you can’t trade something, just send me a letter or a postcard giving some info, or a poem or a sketch or any impression you like. One of my original subscribers sent me an email that she was sending me a check to put toward my expenses, not necessary, but the fact that it’s a check coming snail mail instead of some cash transferring app of some sort felt in the right spirit of what I’m getting at.
“Hey mister postman”. Cheers!
