Trying to replace a curtain I shrunk in the wash 
. My curtain pole is about 130cm long (exc. finials). It is one curtain across a set of french doors. Am stumped as to what size width I need?! Loooking to buy ready made and have them shortened a little if needed. Have found some I like but they are 160cm width - that's not wide enough is it?? Don't want it to be pulled/look tight when it is shut. Sorry to be such a ditz - we had them made to measure originally so I've not got a clue - can someone help!!!
