Armarinhos Fernando, Sao Paulo, Rua 25 de Março
When I was walking through Sao Paulo I found the very large store "Armarinhos Fernando" where you find nearly all things you need for crafting. They sell zippers, buttons,... a lot of sewing material.
But the best items are cotton yarn of different brands for knitting . You will get these for reasonable prices. I love cotton yarn "Anne 500" from Circulo. I used it for the crochet dress:
Also "Clea 5" , mercerized cotton, is also nice for crocheting.
If you prefer embroidering you will find there nearly all colours and different brnds of embroidery floss.
Another shop in Rua 25 de Março sells feathers, borders,
In the whole street which is located near metro Station Sao Bento you will find different shops for fabrics, yarns, laces,...
I will enjoy the next stop in Sao Paulo.
