It is called Rosa Pomar and the address is: Rua do Laredo, 61- 2 esq. (second floor)

They have great Portuguese yarn, gifts for sale, quilting classes and some fabrics, including a little bit of Portuguese fabrics.
I did buy some of the hand dyed yarn and a couple of meters of Portuguese "Chita" that is a type of cotton fabric that I know well from growing up in Brazil. The staff is very friendly and gave me more ideas of where to go to see and buy wonderful items made in Portugal. I don't have a photo of the stuff I bought. So, it will be another post.
