• As per Aroogah's link, I used ferrules. I don't have a crimping tool, so I lay it on a bench vice and used a blunt cold chisel and a hammer to crimp them.
    I can loop it up into a circle of about 15cm that can then be pushed into an oval as my pocket is rectangular. As it is wire rope it does have a bit of spring to it so it isn't as "squashable" as other alternatives.
