Fairy lights

[JMAngel1]

Talk to me about fairy lights - I want to put them across patio door windows in a grid like fashion but I don't have a plug near said window - would also like some down the bannister - no plug again. Do I use those battery box ones - if so, how bright do they shine and how fast do the batteries lose power? Also where do you hide the battery box and how do I attach them to windows/bannister?
Sorry for my ignorance - I've only put plug in fairy lights on a tree before!

I've used battery ones on my stairs this year. I bought copper cookie cutter star shaped from b&q. I'm using the very cheap aa batteries from pound land (think they're Kodak) and so far they have lasted a week, but they need replaced today I think. I have just fixed the battery box to the back of the rail with bluetac.

I pinched an idea from a friend and have got these down my banisters. They are battery operated and look really pretty.

Whoops!

Rechargeable batteries are the way to go, an expensive start out but very quickly work out cheaper. I use rechargeable batteries in all my remotes, lights etc.

How far is the socket? If not too far some lights have a very long wire.

(by lights I mean fairy lights, not lamps etc lol)

Thanks guys. Right off to shops - Little DDs will probably tear them all down but I'm determined to make the house all twinkly a la Nigella!
