Yeah, but it is an Archival Manila Folder?

I mount my pt/pd prints on board using "dimensionally stable, pH neutral adhesive tape" also known as Scotch magic mending tape. I use a "T hinge" mounting where a small piece of tape is mounted on the back of the print and extends about 3/4" above the top corners of the print. Another longer piece crosses the "T" and tapes the tape to the bottom board. I wouldn't use dry mount, adhesive or anything that permanently attaches the image to the board.

The big question is how big to cut the window matte. I don't mask around the image, so my photos show the coating rod outline. So, you have the choice to show the full coated (rough edged) area, only show a small 1/4" black margin around the image, or crop to the image edge. I've used all three....

That's my opinion. You should have at least one opinion for every person that posts...
