This is my second time creating a duffel bag from this pattern, and I haven't had a problem with it to date. The bags produced are able to take a beating, and still draw a lot of attention for their looks. So what's their overall best feature? They cost about 5 bucks to make!
Step 1: Materials
-An Old Sail, or some form of sturdy material. I would highly recommend using canvas for this project, as it is a sturdy and durable material.
-A Carpenter's Square, or some form of measuring tape. A square will pay off when you need to trace out rectangular shapes!
-A Circular Object, I used a mixing bowl, this will be used to create the patterns for the two circular ends of your bag!
-A Zipper, its length is dependent on how long you want your bag to be.
-D-Rings if you are planning on making a bag with a shoulder strap
-Optional: Material for the handles I just used sailcloth
