Lance go to your closest Bunnings, look for a box of
Velcro band fasteners Adjustable Wrap. It's 20 bucks for 5m, so if you lose them just cut another to length. It's good for other little jobs around the house and stuff.
Probably best to go straight up and ask one of those workers that try and make it look like he's busy so you don't bother him.(I hate that)It took me a fair while to locate it, just save yourself half hour.
This stuff is only 25mm wide and serves me well. I do believe you can get wide stuff from spot light, but it's not necessary
Hope that helps mate
