Here's a picture of my first-ever preservation float mount. It's a l/e Dr. Seuss print titled "The Economic Situation Explained." The print is floated above an 8-ply white ragmat cut smaller than the artwork. S-hinges pass through the slots in the black Alpharag mat. Stacked frame consisting of 3/4" flat white inside a 1-5/8" flat black frame. Overall mat dimension measured about 38" high by 20-something inches wide. The customer didn't want to get into oversize mat/glass, hence the narrow margins around the print (but the art is just over an inch away from the frame on all sides, per FACTS 10.02, with a sealed rabbet). The shiny stuff around the edges is protective plastic wrap on the frame.

Lessons learned:
  • Cutting slots about a 1/4" wider than the hinges passing through them makes adjustment much easier
  • When using a piece of folded-over mylar to "thread" the hinge through the slot, be sure the mylar is wider than the hinge.
  • The spacing mat doesn't need to be perfectly aligned since it's not going to show anyway
  • .....so THAT'S why they gave me so many blotter squares in the package.....
  • .....so THAT'S why I need so many print weights....
  • Waiting for starch paste to get dry enough on the hinge is about as much fun as waiting for water to boil
  • It is impossible to make a deckled-edge item appear square
  • Remember to charge extra for float-mounting

Did you use museum glass on this? Where is the outer moulding from?

I can add one more thing to your list -- take your pictures before putting on the glass, so you don't have to worry about reflections.
 
Nice framing, Natalya and I agree with j Paul that the 1" wide mat looks just fine. Thanks for the 'live and learn' tips that you posted. I always find them quite helpful.

How many 'S' hinges did you end up using on the artwork and where did you place them?
 
Nice work, Natalya, and thanks for doing the research for us!
 
Your questions answered

Yes, we used museum glass. The customer had a tough time deciding between the ConClear and the Museum because of the price difference. We originally rang up the order with ConClear, but he e-mailed me back the next day asking for Museum instead.

There are 3 S-hinges along the top and 3 down each side (1 about 4" from the top, and then the others spaced about 12" apart down the sides). The print was on pretty heavy paper, so I wanted to be sure it had sufficient support while floating.
 
Nice work! I looked at your web site and found your page on visualization interesting. Now I want to have a visualization page!
