i don't dry mount because i was always under the impression it was an unreversable situation. when i used to show a lot and part own a gallery, i would 4ply sheet with archival corners for the print and make a window out of another sheet of 4ply. i usually "top weighted" the image ( centered the window, but raised it an inch so it was off-set ) and i also left a little bit of a white border around the image. i worked in a frame shop for a while and liked how this sort of presentation looked. i also make series-images into japanese bound books. sometimes the images are the book pages, sometimes the top edge of a trimmed image ends-up being rice/wheat-pasted onto a rag paper page.
