What can I do with dried roses that I want to keep intact?

I have two dozen roses from my ex/current best friend.
One set is hanging upside down from my ceiling with a spot light shining on them, making the flowers and the shadows an art piece.

The other set dried standing up in the vase, and I’ve left them there for the past two years and they still look amazing.

But I’m going to be redecorating and want to do something with them so I can keep them and display them without having to break the petals apart or something.

So.. how can I do this?
