Lazy carpet laying: Move furniture to one side of the room, install carpet in other side, move furniture over the roll (tricky) onto the new carpet.
The furniture rollers are useful, but with uneven floor it's best to use only three of the four, else one pops out when you hit a low spot :)
Not going to bother with skirting board. Don't want to pull out the existing and make a mess and don't want to put a second layer either. Mostly hidden by curtains anyways.
