In Jim Miller's Clear Film mounting class he shows an assortment of travel brochures in an irregular arrangement. The whole thing is then wrapped in Mylar-D.
I wish I could figure out a way to describe the steps. If you can, make the arrangement face down. the entire front is a continue piece of the film. At the end of each piece cut a generous flap of mylar that can be folded around to the back. In the triangles in between items cut slits that divide them equally so that those can be folded around and taped to the large flaps.

Clear as mud, right?
Oh, for CA's sake, does anyone have a photo of such a thing to post???
