Interior Designers - Wallpaper Trends & Tips Kitchens Bedrooms Baths

JOURNO REQUEST I'm looking for designers to provide commentary for a trends-based piece on wallpaper… How is wallpaper currently being used across kitchens / bedrooms / bathrooms...Is it back, did it go anywhere, what are the trends in wallpaper in terms of patterns and colour but also use? Also tips on how best to use it depending on environment (especially kitchens and bathrooms), as well as considering things like scale, proportion etc. Accompanying lifestyle imagery illustrating relevant points is also welcome. (Pic of my latest bathroom project - covered in wallpaper, naturally.)
