This project has been banging around in my head for weeks.  I knew what I wanted – to blow up one photo big enough to cover a wall.  I checked into having it printed at a specialty printer – um, no thanks, I’ll hold on to my hundreds of dollars, thanks.  So I cropped and blew up the photo myself, and printed it at home on our great photo printer.  Second, I figured I was going to decoupage the separate pieces onto our wall.  Got a bunch of white glue, even bought a tool to smooth out bubbles in the paper.  I think I tried 5 variations to no avail – the wall is not conducive to decoupage.  So after pulling off bunches of paint, and getting glue all over the wall, I opted for Keith’s suggestion of a bunch of frames.  This photo doesn’t do it justice…there are 15 8×10 frames, each one containing a piece of the photo as a whole (systematically numbered – columns 1-5 and rows A-C).  That was the easy part.  Then came the math – I got a straight line (very hard for me to do) for the top of the project.  Measured the exact location on the back of the frame where the nail would sit when the photo was hanging (4″ in and 3/4″ down) and mounted the first photo.  1 1/2″ between each frame (all sides) – but I still got it up in a day, and I’m DAMN pleased with myself!  And yes, I took that photo at night in Rome, on the street near the Colosseum where we were staying.  :-)
