Mimsnet At the moment, Ikea have reasonably decent sets of white LEDs on a solar panel for power - we've got 1 string on a tree in the back garden which are lovely (DH will put the blue, mains electric, led strings on the front garden tree in December).
Our tree and decorations go up reasonably early - occasionally last weekend of November (while watching the "Late Late Toy Show" - an Irish traditional start to the season for many's the long year!! [FGRIN]), the latest is normally 18/19th. Only come down on 6th January (although last Christmas, it was 3rd as that was the weekend and DH really was fed up - I was allowing him to take the lead on all things Christmas last year after DFIL, but we will be back up to at least near normal levels of festivity this year). I also want to put out the big crib this year - which means I can put the baby in on Christmas Eve night, the regular crib has the figures glued in.
