In Poland one store has a few cottons for about $7/meter for the cheaper fabrics. There are some higher quality cottons that people use for making the folk costumes out of it. They are $15/meter--but they are gorgeous! They come in about 4 colors--black with pink flowers, blue with pink flowers, off white with pink flowers and green with pink flowers.
I've seen on line the more expensive imported fabrics from big names for probably about $5 for a fat quarter.
