Jed found this article, which gives several great examples of framing methods:
The giclees have a beautiful deckle (rough, fibrous) edge. They would look great framed with some breathing room, which allows those handmade edges to show. Because the Japanese paper is slightly translucent, it's best to layer a white board behind the print. If it's mounted over a dark background, it won't have as much brilliance. Jed personally thinks they'd look cool "floating", mounted on a thick board, which allows the paper to stand out in 3D space.
David prefers to keep his woodblocks in portfolios or tabletop boxes. This allows him to pull the prints out and enjoy them as 3D art objects. In Japan, there is a tradition of changing framed art with the seasons. For this reason, some people display prints on tabletop stands, which they rotate periodically.
