A quick and easy way to reuse all sorts of bags, including those with no handles, or handles torn off, fabric or plastic.
Makes it easy to hang or carry the bag.
Very robust attachment with no holes or excessive stress points.
Make a circular cord loop using the square knot ( aka hercules knot ), make 2 noose loops, tighten these around 2 smooth spherical objects wrapped in the bag's edges, done !
This will not tear easily, and can be reused.
