Step 9: Finish Top Edge
Almost done! The last bit of sewing is to finish the top edge. In this particular bag, my outer shell already has a finished edge as it is the waistband of pants, so I made my lining fabric a bit taller to allow me to fold it under for a clean finish.
Pin the lining under, and sew around the top of the bag.
If you choose to bind the top of your bag like the cargo one in the third main image of this instructable, take a 1.5" strip of fabric, lay it down along the outside of the bag and lining aligned to the top and, sew 1/4" from the edge. Then fold around to inside and tuck under, and sew again for a clean bound finish. Also, many commercial bags use nylon ribbon folded in half as a binding, this is an option as well.
In both bags I made, I had a belt loop integrated into the design to clip it to my harness. If you are making yours from yardage instead, you will need to add a loop on the opposite side as the cord so you can clip the bag to your harness.
