Unfortunately this will be very disappointing to those of you who simply admire letterpress rather than print, but there is a letterpress print exchange starting up for printers and I am hoping to spread the word.
So for any of you who have a press and want to trade prints with other printers, you can find out all the info here. The exchange is being organized at swap-bot, which if you don't know, is an interesting site filled with a plethora of exchanges from holiday cookie recipes to handmade postcards and so much more. If you print, I hope you will sign up!
