Where can you buy isabella awning curtains

I am a newbie to caravaning & cant find the answer - so looking for some expert help. When I (sorry we) purchased our new Sptite Major 6  (6 weeks ago) we purchased it with an Isabella Opus 250 awning (good deal apparently). All has gone well but we dont like the fact it came with BLINDS & not curtains. The blinds are ok but what a faf, I think it may look better with curtains. That my problem - where do you buy them?
