If I was living in Paris, I would go to RRose Selavy to learn how to knit, sculpt, play the piano, draw some mangas, make some mosaics and some (hopefully) pretty ceramics and a lot more...

RRose Selavy is a 300m² beautiful, creative space located in the centre of Paris in what used to be artist workshops at the beginning of the century (so plenty of gorgeous windows like the one I loved at MERCI). They have classes for adults but also for children.
