1950s-style Stitch Leaf wallpaper by Habitat
There are some nice styles in Habitat's current wallpaper collection, not least this Stitch Leaf wallpaper.
There are three different colour options to pick from, each pared with grey. Take your pick from the kingfisher blue shown above, the yellow you can see below or a hibiscus pink.
The paper is reasonably priced too, at £15 a roll.
