Scratch and sniff wallpaper? Two concerns: (1) Does all that scratching and sniffing leave a mark? and (2) What happens when the scent of bananas and cherries starts to fade away? Are you left with the aroma of rotting ambrosia salad?
Other than that, I'm totally digging this tutti frutti wallpaper from Flavor Paper. Also available in tasty banana and cherry scents at (gasp) $450 a roll.
