If you haven't got time to visit The Modernist magazine's pop up shop in Salford, they sell some of their wares online too – including these 1960s architectural cushion covers.
Just the thing for you if you happen to love 1960s architecture (as we certainly do). The design is based on original architectural drawings from the era, with the covers sized at 58 x 58cm. The only downside is that the cushion isn't included, but they should be easy and cheap to source.
£25 is the price for one of these.
