Picture of Homemade Messenger Bag
We call messenger bags "Jack bags" because Jack Bauer of 24 made them look so cool.  This one got thrown together with some household items, so it's kind of a MacGeyver/Bauer hybrid. 

It's cheap, it's easy, and you'll never cry if you wreck it.  It's the Jack Bag!

Step 1: Tools & Supplies

Tools & Supplies:

Scotch tape
Duct tape
Xacto knife

Stuff not pictured because I'm disorganized:
Magnetic tape
Hole puncher
Iron-on patch compound

Step 2: Make a paper stencil/guide

I guestimated where to start, so a paper mock-up helped me figure the dimensions.  First, I taped lots of pieces of paper together.  From that, I cut two rectangles of paper and a long strip that would go in between them.  I taped the pieces of paper together and played with the measurements. 

I ended up with the front and the back (the rectangular pieces) being 11" x 13".  I also rounded the bottom of this piece for purely aesthetic purposes.

The long strip that connected the front to the back (and makes up the bottom and sides of the bag) was 3" x 36" (I cut it extra long; better too long than too short).

When I was satisfied with the dimensions, I cut the model apart so I could use them as a pattern on the cardboard.

Step 3: Cut out your pieces

You will need two of the rectangular pieces and one of the long strip.

Step 4: Start assembling

Prepare the long strip by bending it in half long-ways.

Starting at a seam, use duct tape to attach the thee pieces together.  I used two ways to join the pieces at the curved sections. 

At spots where the curves were, I used skinny pieces of tape so that it could follow the curve (I included that in one of the pictures).

Step 5: Make the flap

Cut the paper guide down just a tad so it is smaller than the main body of the bag, trace it out onto cardboard, then cut it out.

Don't even ask what Jack Bauer would do for a Klondike bar...
