I searched yarn stores on Ravelry before going to Paris and one that I actually visited vas Le Comptoir.
The interior was from ca 1861 and this is what I want my dreamkitchen to look like
It´s cituated on 26 Rue Cadet that is very much in centrum of town. I walked from Lafayette with a broken toe....
She had a lot of cute sewing notions too!
I also went to Sweatshop Paris but on a monday so it was closed but looked like a very inspirational sewingroom ( with a lot of machines ) from outside
