i've always had nets, they got grotty easily as we lived near a busy road, so always washing them. Getting them to hang right was always a flaff too.
we've now moved to a very quiet area, no road near by and there are vertical blinds and i must admit I love them. 
Am i still in the honeymoon phase or will i be tearing them down any time soon and gnashing my teeth at the blasted things.?
