We've got a room in the house that is tiled red and white. I think it's OK. But it has been suggested that it should be carpeted. So eventually, after being told several times, I emptied the room and decided to carpet it myself. I am after all an expert at everything.
I bought one of those electronic measuring tape type machines. It's a
small box which you place near the wall and it sends an invisible beam
to the opposite wall which somehow measures the distance; and then you
can read the distance between the two walls on the little display
I measured the room in question and went to the carpet shop to buy the carpet.
I discovered the room is three kilometres long and four centimetres wide. The shop manager tells me they don't do carpets in those measurements. Wrong colours too! I wanted a carpet with red and white squares.
