Picture frames that are not hard or breakable?

I took a piece of Foam Core board (Michael's or Hobby Lobby) about 24" x 18". Glued a pretty piece of fabric to it. Then I took pretty 1/4" wide ribbon and glued them diagonally across the board in both directions about 3 " apart (the ribbon forms diamond shapes). The ribbons need to be very snug so you can slide photos underneath them and the ribbons will hold the photos. Foam core is rigid but not hard. I put these on the walls of my mom's room in SNF after her stroke.

Craft stores like Hobby Lobby and Michael's have heavy paper picture frames you can decorate, or you can just make them out of cardboard yourself. There are lots of YouTube videos on how to do it.

Cork board - or taping or gluing pictures onto poster board (the thicker foam style) - I have many reminder signs and such and have used the foam poster board and they lean up well.

the page protectors that you use when you put a 3 ring binder together. You can slip photos into the sheet protectors and either leave them like that or put them into a binder. There are soft plastic binders that will hold them safely.

What about putting them in an album, do you really need the pictures on display?

And I like Pronker's idea but I'd skip the plastic coating, the cost of getting multiple prints made is not really that great.

Many times, I matted any photos with a stiff matte and then covered them with cling film. Good luck.
