Life / Poland's Craft Stores, Yarn Shops and Sewing/Fabric / Clothes Stores - in or near Krakow? [21]

Hi, Can anyone offer assistance. I'd like to get some velvet or chenille material for curtains when I'm in Krakow next Sunday (for few days). Is it possible to get these in Krakow and how much approx per metre.

Ta,
Danny
