The jib now looks like this with it's new UV strips:
The stitching looks ok from a distance, but is a bit wonky close up. But it looks like it will work, so that's the main thing.
As you can see I've added some tell-tale strips on the trailing edge, just to see if they will help me set the sail better. I've done the same on the main sail.
I just need to get them back on the boat now and do some sailing....
