@gilester45 Whoever said you should jet-wash your parasol should no longer be on your list of trusted information sources.

I've got several of these things for... reasons... and one thing I've noticed is that they tend to be quite strong at first, but most of them weaken significantly after repeated exposure to UV (e.g., the sun, especially if you live in a hot place). I'm in North America, near the Canadian border so the sun is never truly direct, though it's close for part of the summer. One year I had a couple of these out all day every day for about 3 months. At the end of that time, they looked OK but just picking one up, or pushing the fabric with a finger, would tear it. They were like gauze, but weaker. They might have taken a jet washing in the first few weeks, but probably not after that.

There are some made with special UV-resistant fabric (I think Sunbrella is one brand) that lasts much longer in the sun, but those will cost quite a lot more.

Final note: it might not be beautiful, but you can patch that with a piece of fabric (perhaps cut a piece from the bag it came in, if you don't need the bag anymore) glued to the spot with transparent silicone caulk or any flexible adhesive like E-6000. However, test the rest of the fabric; if it's weakened significantly, that might be a pointless exercise.
