Yes Gizmonster I like the idea of the blinds and curtains set-up like you have. It's a good point you make about having your vertical blind at a 45° angle during day time just to give you some extra privacy and then to close both the blinds and curtains at night. If I do go for a vertical blind, I may try leaving the blind fully open during the day as I do like the room to be very light.
The difference I have to you is that you close both the blinds and the curtains at night even though you don't really need the blind because your curtains are an ample thickness, where as mine are not so I would need to close both to ensure I have complete privacy.
I'm having some friends round for an evening shortly, so I'm looking to get this sorted quite quickly, I guess it won't take long, it's just a matter of me not taking too long over deciding which type of blind to go for!
