If only wallpaper manufacturers would note on the back of the wallpaper where the match is... It had been years since I'd hung wallpaper and while the paper wasn't that hard to work with - I had a really hard time finding the match.  I was hanging in a small bathroom with a lot of turns and tiny drops to the floor, so this project was a pain.  The end result looks very nice, but if gift wrap manufacturers can add clues on the back for cutting, you'd think something this expensive per roll could add some visual clues.
