Ready-made curtains

.. .. my folks are coming to visit and i'm trying to get my pad sorted before they arrive tomorrow. I urgently need to buy a pair of ready-made curtains for the bedroom window (90cm X 90cm). i've been to ikea, no luck. not particularly fussy, just need something to block out the neighbours opposite so my prudish folks don't feel watched when they strip off at bedtime. no time to run up my own, so ready-made is essential. any ideas ?

Mömax in the Euroindustriepark.
Möbelum on Leopoldstraße.
Curtain section upstairs at Hertie (second-from-top floor?)
