Catherine, from your drawing on the cardboard you are going with a tower of rock?? Very cool.....IMO drilling the rock to fit on PSV piping is more secure and looks better than zip tieing all the rocks .....if you are doing a tower. You may have to zip some rock but keep the larger ones secured by drilling and placing onto a PVC structure (or something secure)
I tried using too big of a drill bit to drill the rock and I broke a couple of rocks before I figured out to use a small bit and drill the outer circuference of the hole in the rock to fit onto the PVC. If you go this route.....just a hint.
Everything looks awesome!!
