Another good thing about messenger bags is that almost anything can be made into one, including mailboxes. In this Instructable (Which is my first one), I'll show you how to take almost any old mailbox and turn it into a very usable and stylish messenger bag in only a few minutes.
Before you begin, you might want to make sure you have a few of these materials lying around:
An old mailbox (Post mount boxes work better then wall mount ones)
An old strap or fabric to make into one
An old towel your willing to get dirty
x2 Screws (Not to big but not to small)
Step 1: Finding a Mailbox
But, if your more like me and don't have a steady supply of mailboxes, then the best places to look are in the trash and in thrift stores. Both of these places are filled with things you would never expect, and there are usually quite a few mailboxes in both of these places.
I found the mailbox I used for this Instructable in the trash. There were about ten there, because an apartment complex was doing a major renovation to their buildings. Which involved throwing away all the tenants mailboxes for no apparent reason.
