Can you sew a bit? Either hand sew or a machine, it doesn't really matter. If you can, follow the pattern at http://www.saltwater-kids.com/2008/10/retro-duffel-bag-tutorial.html but scale down your two circles to no more than 5 to 6 inches - mine are 7 and are just too large. Ignore the bits about attaching zippers, you can just sew the top closed instead.
You will also need to change the width of the fabric to match your new circumference (the example uses 8). To do that d = c/pi where d is your new diameter and you end up solving for C. IE. your diameter is 5 giving you the equation 5 = c/3.14 which gives you a new width of 15.7 (if my math is right). The length - just shrink down to the width of your sling bag, you don't need to do any math for that.
To make the hazard symbol on the bag, depending on your fabric, you have a couple of choices.
1. Sharpie the image onto the fabric.
2. Iron/glue on fabric cut in the shape.
3. Sew on fabric cut in the shape.
To make the hazardous sign you have the same three choices. When I made mine, I used black bias tape, yellow paint pen and a stencil and glued it where the zipper would go.
I also used cardboard circles on the ends and stuffed it with pillow stuffing.
The straps I got from REI as they have replacement backpack straps which is what you need.
If you have any questions, let me know!
