How fabulous is this Nina Campbell wallpaper in my friend Tess' kitchen! Some people are worried about the longevity of hanging wallpaper in the kitchen due to possible water and steam damage - but if you keep the paper a little away from the sink and stove (as Tess has done) and if you have good ventilation - you shouldn't have any problems. 

If you want to play it extra safe - choose a hard-wearing vinyl (which you'll be able to wipe down) rather than a more delicate paper.
