Using a few 6' lengths of 2" x 1" rough, and the standard Gleipnir, I tied the first on one end as normal, then three more by doubling one tail each time, which gives a loop on each of the three.
It works well, with the added bonus of using the two loops in the middle for carrying the bundle. Using two of the loops as handles will prevent the load from swinging as you walk, thus protecting your legs from being bruised.
I don't have a photo yet.
