Things You'll Need:
- Plastic Bags
- Iron
- Wax Paper
- Sewing Machine/Materials
- Old Book Bag with buckles
-
Step 1
Use larger plastic bags like trash bags or department store bags that you have laying around the house.
-
Step 2
Pull out your iron and ironing board. Now you want to cut the bottom out of the bags you are using and turn the printing inside out (or it will become very messy). Place the bags in between two sheets of wax paper and begin the melding process. Make sure to stay on the wax paper otherwise you may harm your iron. Also, ventilate the space your working in with open windows or fans. Finally, make sure all of the air bubbles are gone to ensure a reliable material to constitute your messenger bags.

Step 3
After you have produced enough material by melding plastic bags, begin stitching them together. You can find designs off the internet if you cannot figure out one yourself. Make sure that you sew up all the side flaps on your messenger bag so that things do not fall out.

Step 4
The last step is sewing on the belt buckle strap to wrap around your shoulders when you are riding your bicycle. Find an old book bag that has buckles on it. Cut off the buckles and stitch them onto a strap made from the melded plastic bags.
