"i enjoyed your paper" card
I never got to use those old reprint request cards but always wanted to (cool history here). So instead, I made "I enjoyed your paper and wanted to let you know" cards. You can edit them (on any graphics editor like Photoshop or free online versions like Photopea) and print them (I used an online printing service like Vistaprint or Moo so they are on cardstock; they are the standard 6x4" postcard size). If you need help, reach out and I'd be happy to help.
