So I have my original image and my mirrored image that I printed on front and back/1 sheet of paper. When I hold it to the light, I see that it's uneven.

I'm working on a project for my aunt. She wants it on copy paper, then laminated and cut out, leaving white space around the image. She wants to put a dowel in it to hold it as well.
