Antoinette Poisson is a Paris-based company which designs and manufactures hand-made domino paper. They sell beautiful wallpapers and boxes featuring their domino designs but I particularly love their posters which, placed in a simple frame, can really liven up a room.
Also wonderful are their notebooks if you, like my friend Emma, are sick to death of journals that have hateful covers featuring detestable scenes from twentieth century paintings that nobody likes.
They have a beautiful store that you can visit in the 11th district (12, rue Saint-Sabin) and will soon be launching an e-shop! Swoon.
