Whenever I'm in Paris I have to visit Graine d'Intérieur. They have such beautiful and detailed furniture and home decoration items. I know it's impossible for me to buy most of it as I live in Denmark, but it's definitely worth a visit. You can buy lots of knick knacks for your home. Last time I bought fake spots of flowery grass as well as a beautiful photo album. Their website is in French but have a look anyway Graine d'Intérieur.
