We have wallpaper on the Post this week, beginning with a superlative design by William Morris (1834-1896), the master of the repeat pattern. The William Morris Gallery, which is housed in what was once Morris' family home in Walthamstow, has a new exhibition from 5th April which brings together a huge range of objects decorated with his enormously popular patterns. But for many, it is still his textiles and wallpapers that display his genius best. This is 'Pimpernel', designed in 1876.
