Comments

Although you didn't specifically discuss it I'm assuming you cleaned the rock from dust/dirt.  Also is an application of a mold release needed?

I like the idea of creating my own mold.

The rocks peel out of the molds with very little effort.  No release necessary.

It's probably a good idea to brush off any dirt since some of the larger particles will stick to the latex and may cause the mold to rip when it is removed.  However, if the dirt looks like natural talus you might wish to leave it in place even if you have to pick it out later.  I've found that coating several rocks at once is an efficient way to work and gives you the luxury of experimenting with this type of thing.  Painting rocks with latex can also be extremely addictive!  I did about three dozen at once with the latex that was leftover from this session with Miles.

Instead of using cheese cloth what about using the fiberglass mesh tape that is used on drywall? It would be water proof and stronger because it is made of fiberglass.

Drywall mesh might be a bit too rigid to conform to the shape of the rocks.  I've had excellent results using tolle, which is inexpensive and easy to find at fabric stores.
