A solution to displaying a collection of small pieces of origami as a keepsake was to arrange them on a patterned textured mountboard.  this was then placed in an oak box frame lined with the same board creating depth enough to allow the 3Dimensions of the folded paper to show.  The principals of this type of framing would make it ideal for many other types of keepsakes and memorabilia and an ideal way to admire a small collection of treasured items.
