Everything is recycled stuff:
a) the buttons (from a jacket that went moldy)
b) the lining (from a batik top when I was doing touristy stuff when I first arrived in Spore)
c) the interfacing (well, not really interfacing but a clear plastic folder which I found at home)
Okay, the thread used to sew the bag is not recycled (that would be impossible!).
I now use it to carry my wallet, mobile and tissues when I go out to lunch at work.
