I have two rockers that need the seats repaired and I don't know where to turn to get it done. I live in the mountains of NC and had hoped I could find someone who makes rockers. However it seems the ones I find all use wooden slats for seats and I definitely want it to be roped like it was originally. They aren't antique. They are only about 30 years old but the chairs are in excellent condition otherwise (and are extremely comfortable!) They have always been kept outdoors but on a covered porch. Any advice?
