Tying stuff up with romex, that is, the electrical cable used in house
wiring. My old locked angle Celestron tripod came with a BORB to keep
it folded up, but this wore out many years ago. I ran through a number
of less than perfect things to tie it up until I hit on the electrical
cable... it holds it's shape, it isn't springy, and it has a padded
covering.
