Jamie, that card looks ingenious... but it's kind of the wrong way round to my mind... you'd maybe have to know roughly what rug you've got and use the card to double check it, rather than using the card to start off from not knowing anything!
Very good though I've never seen that before.
Simon I have no wish to watch your neighbours sh**ging and killing each other, interspersed with trips to the same old pub that hasn't been decorated since 1963
