I print my Vampy images four-up on this label stock then mount them on a medium weight cardboard backing before cutting them apart into 3" w x 5" high display cards. I then add a small cardboard stand to the back as well as a description and price before offering them to my galleries...
See description above.
The trick is manipulating & sizing the photos before printing. My printer is an EPSON Workforce WF-2630 and is not included in your list below.
