I love fairy lights but am never sure when to use them. The children are in their rooms for about ten minutes before they go to bed so it hardly seems worth it to turn them on then - and they look pretty rubbish if they're off all the time.
I don't really want to leave them on whilst they go to sleep because
a) they don't have night lights
and
b) possible fire hazard
and
c) unnecessary waste of power - unless I suppose you use a timer switch?
Have they a point at all?
