Fix backpack

I'm fixing my old backpack by myself. 

I'd used the backpack more than 12 years. All of band's materials were damaged. So, I decided to change the place of the material.

At first, I challenged to fix the most difficult point which was at the bottom of the body. 

It was needed about 2 weeks to fix only it. 

I like to use gears for long while with fixing.
