Compression straps of some sort make sense.
Heck! you know how to take the wind out of a guy's sail. I thought I finally had an original idea

I have also been doing the same thing to fabricate my own bungees. They do work really well. I use two to hold my rackpack and other important material in place, especially when touring in July. I carry a couple of spares just in case.
