Flatten your prints my slightly moisting then on the back after they have dried and put between some smooth mat board and weight them down with some heavy books. In 24 hours they will be as flat as using a press.

Hing mount then and put overmats to keep it in place.

Look into the display shelves that light impressions sells.
My wife likes this in our great room.

Now she has seen prints that are float mounted and wants me to start doing everything that way.

The way arround this is print with large white borders and over mat with 3/8 tth to 1/2 inche of the borders showing. Works for me and I have a dry mount press. Not every picture is worth drymounting!
