I've been repairing some clothes recently - it's an environmentally friendly activity that helps save money and resources and I find it quite relaxing to do some sewing. The photo shows the buttonhole of one of my scruffy pairs of trousers that I wear round the house. The buttonhole had ripped apart, but otherwise (apart from being faded) the trousers are perfectly wearable and very comfortable. I don't know how well it shows up in the photo, but I mended the buttonhole by sewing two thin strips of ribbon round the edges. One strip on the outside and one on the inside, fastening them both firmly to the bit of buttonhole that was left. So far this is working and I'm wearing the trousers again quite happily.
The other story of repair is not so successful. My favourite summer trousers for round the house had developed acouple of small holes in the seat so I repaired them by sewing patches over them. The patches then ripped off and the original holes expanded so I patched everything up again but it all ripped dramatically apart again the next day, the trousers now have huge holes right across the seat (and it's not as though I'm putting on weight or anything!) So I think I'm going to give up and reuse the fabric to make something else!
