Blimey, it's a giant leylandii! You'll need to cut a hole in the ceiling though. Otherwise where's the fairy gonna sit? (You've got to have a fairy on top of the tree. It is Chrimbo after all.)
PS - I think there might be a dead bulb round the back. It'll only take an hour to check them all won't it?
We didn't realise the tree was gonna be so bloomin' tall - had to chop the top off as it was!
The last few weeks its been listing further and further to the side, though, subtly but surely. Good job we "tightened the nuts" today before it reached critical slant-mass...
