a few years ago we had a bad accident when stoking up the wood burner stove – which resulted in a wood ember falling onto our lovely rug – exactly in the part where there was a small section of white wool. fortunately we were recommended magic hand, a specialist company who will not only clean, restore and repair your rugs, but will pick it up and re deliver it and find the wool to match. it came back within a week and you cannot even notice where the burn was. it was not cheap, but considering the cost of good quality rugs, it was well worth it and a fraction of the price to buy another replacement. we have now learned to roll back the rug when using the wood burner!
