My 35mm strip contact printing frame has a piece of felt on the backing board to push the paper up to the film. A piece of foam would work too.
I've found a site that shows how to make one...but it's nothing like what I've ever used. The ones in college were metal - and a hinged lid that held down the negatives. I'll experiment a little more this evening. I'll try the felt, though, as part of the sandwich.
I love the smell of fixer in the morning...It smells like...PHOTOGRAPHY!

It would be great and work wonderfully...if my floors were even. lol! I ended up making the contact print sandwich doing the same thing but using an old book for my flat/even surface and an LED flashlight with a t-shirt wrapped around it to soften the light. *sigh* I need to find a spot in the laundry room or bathroom that's got an even floor. This house was built in the '20s and hasn't settled evenly.
I finally got the process to work with a few test strips (and mumbling). I'm sure that I can find a better room to use, though.
You don't need a flat/even floor - that's what the bottom piece of glass is for.
Why do you put the sandwich on the floor? Because it makes it easier to hold the light source far enough away to ensure even light and reasonable exposures.
Adding foam to the sandwich is great, if you have even, flat foam.
I repeat (merely for emphasis) - the reason for the glass on the bottom and the top of the sandwich is that it isn't particularly hard to find two pieces of flat glass.
“Photography is a complex and fluid medium, and its many factors are not applied in simple sequence. Rather, the process may be likened to the art of the juggler in keeping many balls in the air at one time!”

...Since the top of my washing machine doesn't sit even, I then put the paper on top of a rather heavy book (an old hard bound that will end up in the Goodwill pile), the paper on top of that, the negative and then the double glass...
For best results, ensure washing machine is not running at the time...
