My husband told me that his pocket had a hole. So, I repaired it.
First, I cut off the damaged area.
Then, I added a new bag for the pocket.
That's it. Since the home was quite large and the other areas of the pocket were worn and very thin, I decided to replace the bottom part of the pocket this way. However, if you notice the hole when it is small, then a repair can be just a simple sewing up the hole or patching it. In this case, this drastic measure was needed.
