Okay, here is A solution... You can buy a dye from the USA which you dilute and spray on the carpet, it's colourfast etc - available in 20 different colours $9.95 from
http://www.goestores.com/catalog.asp...&DeptID=198128 . Went through the order process however found that on top of the $30 postage there is a $20 money tranfer fee! My inlaws are in the US so I thought they could bring it back but of course liquids are a no-go and if it burst in their luggage I wouldn't be popular!
So anyone want to go in with me and order a few bottles?
