I got a nice light peach sofa that has some tears by cats and smudges since the prev owners never cared for them but I wonder if I should get them re-painted to start treating them as they should or should I just save my money and buy new ones?
It depends on the quality of the sofa, and the cost of the repair or recovery job. Go price new stuff of the same quality, and then ask a reupholsterer what it would cost to repair it.
