I would love plain cards, cant find any. The cards I purchased came from Michaels and the Dollar Tree during the holidays. They were either $1.25 or $1.00 for a pack of 8 - 10. I dont use fabric I bought "stiffey felt" which is just stiff felt so it slides into the photo opening. Easy to do. I cut stiff felt to fit photo opening in card. Hoop tearaway stabilizer and then lay my stiff felt on the stabilizer and hold in place with tape. Then I stitch out . Very easy to do.
