I just found something …There's this shop in Vienna called Madame Kury. I went past it for about 2 years but never knew what it was about. From the outside it looks sooo nice but I was just not sure if it really is a shop and what they sell there. Sounds stupid, doesn't it?
Well however. I just found the shops website.
And it's not only a shop! You can also rent a sewing machine per hour (7€) and per day (30€) and they have sewing workshops (~35€ incl. material).
