Since the 1870’s a manufactured type of caning has been used in seat frames.  The cane strips are woven into panels.  These panels are soaked and then tampered into a groove in the seat frame.  Once damaged they cannot be repaired but will require the old panel to be removed and the groove cleaned out and a new sheet fitted and secured with a reed spline. I can undertake these repairs. An example of a finished chair is shown This required particular care as the finish was a modern black foil.
