Hi, I've just bought a large wallpaper mural of new york city at night but the instructions say starting from the left, each panel must overlap by 1cm for picture to match up?? How can I get around this without seeing 5 unsightly seams?
I would say "with great difficulty".
However, here is a suggestion.
Paste the first panel in position and, as soon as possible, paste the second panel and align it as carefully as possible.
While both panels are still damp, take a metal straight-edge and a
sharp craft-knife and cut down the centre of the seam.
You should then be able to remove the 5 mm overlap from the second panel, peel back the edge of that panel, remove the 5 mm underlap of the first panel then re-smooth down and roller the second panel edge.
Repeat for the remaining panels.
If you run out of time at any point, make sure that the right hand edge of the remaining panel is
not stuck down. When you resume, re-moisten this edge, stick it down and proceed with the next panel.
Make sure that you always use a very sharp blade and be very careful of your fingers.
(If you are going to have to cut off
some of the top or bottom of these panels, you could cut off
part of this from the first two before you start and practice on these samples before proceeding with the entire job.)
Good luck.
