This was one of our carpet repairs in Sydney in a residential home. The pet damage to the carpet was caused by a cat pulling at the loops with its claws. I re-tufted this area with a needle and some of the same yarn by hand. The challenge is trying to make the same loop construction that is like the original which was machine sewn. Hand stitch is never as perfect as machined stitched but I can get it close. The customer loved it. The yarn that we stitched in was new and needed sometime to wear in and become a little soiled similar to the rest of the carpet. Once this is done you will never see where the new yarn was sewn in.
In this residential job in the Sydney Metropolitan area. The damage was caused by a dog. I had to cut out the damaged area and replace it with spare carpet the customer had kept stored away from when the carpet was first installed. The challenges I faced was trying to match the carpet perfectly so the joins would not be visible using a process called invisible mending. It was also on a join so repairing carpets on or near joins can create other problems.
