Step 1: Collecting the materials
Next, actually go the junkyard to get your materials (you’ll design your bag based on the stuff you find, and you can always go back to the junkyard later if you realize you need/want anything more). Take a knife, a wrench, and a screwdriver with you; you’ll need them to cut out/get at stuff you want. At the junkyard, try to get as many large rectangular pieces of leather as you can. I found the backs of seats worked especially well for this. If possible, get as much leather of the same color as you can, unless you want a random multi-colored bag. If you see any cool pre-made pockets or holders on the car, cut them out too if you want, because you can sew them to your bag too. Also, don’t forget to stock up on seatbelts and buckles, at least 4-5 feet of the belts and at least 3-4 buckles. They’ll be important for straps and clips later.
