Ultramod (2-3 rue de Choiseul)
Buttons, ribbons, fabric - worth a visit just for the interior/atmosphere alone. Ultramod is exactly the kind of shop I think of when I hear the word 'haberdashery'.
Opera Droguerie (16 rue St-Augustin)
A strange little shop where half of the floor space is devoted to kitchen gadgets and washing powder, and the other half is devoted to gorgeous things like bags, notebooks and postcards from la marelle éditions. I picked up quite a few notebooks here (with awesome covers by French illustrators Nicoletta Ceccoli, Miss Clara, Lyndie Dourthe and Fabrice Backes), some colouring books for C (including the one below by Nathalie Lete), and a great bag by French designer Mlle Héloïse.
The lovely woman working on the day that I visited had seen G and C continue on down the street when I came into the shop, and she popped a little present for C into my bag as I was leaving. She very sweetly explained in halting English that it was for my little girl. Nice!
Yaya (55 rue Montmartre)
Gorgeous clothes, friendly staff and a beautiful interior with cool signage, exposed brickwork, industrial fittings and fairy lights. How could you not love it!? Since it was sale time and therefore end-of-season in Paris, all most all of the sizes left were quite small and I'm guessing that many pieces had already sold out. I would love to visit Yaya as a new collection hit the shelves!
