what you can find here is everything you need for sewing your own clothes, bags, curtains, stuffed animals etc.
from different sorts of fabric to buttons, ribbons and zips, everything is really low-price (drapery starting around 2 euros per meter). you cannot always expect to find exactly what you wanted but be sure to find other things you never knew you needed.
if you're nice, expect to find a bottle of wine of a box of chocolates in your shopping bag around new year's day.
