Number of Float Hinges

How many mulberry hinges would you use to float a vertically-oriented 16 x 20 on paper? How many to float a 24 x 36? Does the number vary depending on how flat the paper is? I know what we do; am curious about what others do.

If the paper is not too heavy I would think two would be enough but being a "braces and belt" type of worrier I would probably use four. The most important thing is to make sure the hinge paper is weaker than that used for the artwork.

Always as few as possible, but enough to support the work. You know, just the right number.

The smaller piece would get 2 or 3 across the top depending on paper weight and degree of flimsiness. I like Greg Fremsted's design of a fairly tight central hinge with the ones farther out having a longer unattached section so they can have a bit of lateral movement. I usually also add some small loose hinges on the sides towards the bottom to take the stress off the top hinges should the piece be handled incorrectly. The footprint of the hinge on the art is also a variable subject to weight and density of the paper being hinged.
I always use some kind of pass through hinge on float mounts. Sometimes just slits cut in the mount and sometimes I cut a complete mat window and attach the fallout to the back of the art and tape it back into the window opening.

I do his 'one tight and the others a bit loose', as well. I think I use more hinges than most folks. I would probably do three across the top of a 16 x 20, but I tend to do a couple on the sides near the bottom, and a couple on the bottom, from the other direction. This, because I think, 'what if it's sat upside down?' But maybe the side hinges are enough?

This reminds me of my Mother trying to teach me to make pastry (I am useful in the kitchen but still hopeless at this)

"How much milk and how long do you have to knead it for??"

"Oh, you know, you can feel when it is right":rolleyes:

Every piece is going to be different and the number of hinges will veri. If you are hinging a light rice paper piece, 2 hinges may suffice but if you are hinging a heavy poster you may need 4 or more hinges. Another thing that has to be considered is what weight of hinge you are using. There are lots of stuff to consider and to get this "one way fits all" just doesn't work. It is impossible to say especially without seeing what is being hinged. Only experience and practice will answer the question of how many hinges to use.

Agreed. I've done lots of it, and the pieces turn out well. I just wonder sometimes if I'm over-engineering. I always like hearing what you have to say, so thanks for posting.

There is such a thing as too many or too large a footprint. I've repaired a number of hinge jobs done in the 70's and 80's that were almost continuous across the top of the paper. They probably looked great when they were first done.
I see a good deal of damage done to fairly heavy print paper when the hinging is overdone. This may well be enhanced due to the rapid fluctuations in humidity that can happen here.
Anything that restricts the paper from normal expansion and contraction can cause cockling. So the fewer and looser the secondary hinges are, the less likely cockling will occur. If you use bottom hinges, make sure they are loose ones.
