Float Mounting works on paper.

Float mounting photographs and works on paper, help to show the full paper edge with no loss of image.
Works on paper can be "laid on" which is when the paper is attached directly to the moutboard usually from the top to prevent the paper from cockling.
Raise and float is when the paper is raised off the surface of the moutboard to cast a slight shadow and is particularly nice when paper has a hand made or deckeled edge.

When asking to have your work mounted always ensure that you are getting acid free mounts and correct installation methods. Once you are satisfied with the quality and longevity of what you’re getting there are some other mounting methods that one might consider.
