The stitching on the panels has gone, but so far no damage to the actual panels.
Looking for a suitable company who can restich them. They will need to be removed and transported for repair (which I could probably carry out myself).
We used these guys Griesser last year to replace our back garden sonnenstoren (awning) and we were very happy with the result. We chose something from their cassita range if i recall...
So far the two companies that have come back to me say they need to completely replace the material. Cost in the region of 1500chf per blind which are around 5.2m x 2.2m, 3k for the two.
As I'm not working will try the manual sewing route for now, then guess will have to bite the bullet and have the material replaced.
