Harmonie Intérieure is the fantastic online shop selling delicious designs by French couple Frédérique and Fabien. They've created a stunning range of interior decorations, including large format vinyl stickers, mounted photo prints and posters.
Our favourite is this typographic sticker from their Temps Retrouvé collection. You can pick and choose from a range of colours and sizes.
(They've also got lots of lovely images over on Flickr.)
