Hi Bill,
There are so many more options available to you now. You will never have to look at another old canvas blind again.
It also depends on your budget?!
You have options like external straight drop roller blinds. These blinds are usually concealed and protected in fully enclosed powder coated head boxes. They can run on stainless steel guide wires or aluminium channels.
You can also use external shutters, although these can be a bit difficult to operate or get to if they are not on ground level.
There is a great new product out, which is also the latest design and technology in exterior window furnishings. It is a remote controlled or crank operated 80mm external aluminium venetian. But also one of the most expensive.
So it all depends on your budget and style of house.
I hope that helps you a little, but more so to realise there are plenty more options for you now.
