How do I preserve a collage?

[Lynn CC]

I've been taking a lot of my pictures and glueing them to a huge piece of heavy cardboard, I've made 2 collages so far. Do I use hodge podge over the top like a jigsaw puzzle or will this ruin the pictures?
I LOVE These, they came out so nice. After I get them preserved I'm going to have them professionally framed or I may attempt to border and frame them myself if I can find some ideas.
Thanks for your help!

You can use Modge Podge, or I found a spray decoupage medium that isn't as thick and dries really fast. Sounds like a cute project!

I would do a small test project before trying something, if you don't like the look then you are not ruining your beloved project. And if you use the mod podge use a foam brush as a regular brush will leave stroke marks.

Thank You!
I have so many photos, I've got 2 collage's done already. It's amazing how many memories they bring back, I had a good cry for myself
My family and others have had so many conversations about all the pictures too, it's amazing what they have stirred up, LOL
