Art Hinging Tips Part 2
The most time-tested method of attaching paper art in a frame is wheat starch paste and Japanese paper hinges. "Feathering" the edges of the hinge paper by "Wet Tearing" is universally recommended to avoid embossing and cockling of the art.
Pendant hinges used in "Shear" are much stronger than when used in "Peel". In "Shear", the whole bond must be overcome at once. In'"Peel", the bond is overcome a little at a time and has very little strength. You'll have to try this yourself to see the difference.
only on one half of the hinge.
If the frame is turned sideways or is inverted, the hinges will change from the"Shear" to the"Peel" mode and will fail.
If you put two (or more) hinges with "T"s close to the art - the art may buckle between the hinges as it expands and contracts with changes in humidity. Put one "T" close to the art and all the others at the tips of the pendant hinges. Now the art can expand or contract and the long pendants will swing and keep the art from buckling between the hinges.
Additional hinges at the bottom (or on very large/ heavy pieces, even on the sides) will keep the hinges from"Peeling" if the frame is inverted. Shipping hinged art is always problematical and hinging in this fashion should eliminate many of the hinge failures. The bottom and side hinges should be attached slightly loose to allow some movement due to expansion/ contraction of the art and backing board. Hinges will not flatten buckled art but a good paper conservator can usually help. "S" or"Slit" hinges for floating art
This method of hinging is quite effective visually if the art has a deckled edge. Make sure that all but one hinge is"loose".

Floating the art on a pedestal of mat or foam board is another method of framing that shows off deckled edges with a shadow. Use the same method of one tight "T" hinge and all the rest loose "T's". Bond the pedestal in several places with a flexible adhesive to allow for some expansion and contraction and for easy removal.
