I came across this group of trees and thought they would make a great background. The problem is there are no markings on this and it almost looks home made anyway. So searching "THE TUBE" I found video's using silicone caulk and baking soda. Looks easy enough , but I thought I would post here to see if any of you have tried this and what the results were. I'm also open to any other suggestions you may have. Time is short. Christmas layout time is coming. ( yea I said it )

Bruce,
I tried to make a mold of a brick wall. The mold tore into pieces amd I spent days picking rubber (or whatever it was) out of the original brick wall. Admittedly, Operator error played a big role in my experience.
If you find an easy way to do it, I'd love to hear it.
BTW: I'm already working on Christmas too!
Emile

I was thinking of using hydrocal. The video used hot wax. What did you use ?
Guess I'll get the mold made first and experiment from there...

I've tried mould making too but only for small pieces. Before I watched the video, I wondered about using modeling clay for what you have in mind? That's what I used; the advantage was that it would wash off the moulded object if there was any residue left on it (there was), downside was that the level of surface detail was limited. I did not need to use the mould to produce multiple large copies, which is what I think you have in mind.
The video shows using silicone mixed with cornstarch to make what is a kind of clay substitute but probably more flexible. That would be a smelly job and you'd need a lot more than is produced in the video, which might mean it would quickly become difficult to work with.
I can see why rubber/flexible moulds are used in order to get the moulded object out. That tree piece looks like it's made out of Plaster of Paris and if so it came out of a mould itself. In the video wax or resin is used and the latter might be preferable for what you have in mind.
I hope you try the video technique and good luck!

I had watched this 4 part video. Its time consuming but seems fool proof.

Call Harry Hieke, one of the forum sponsors. Harry is an expert at this stuff and can give you some ideas.
Emile this would make a good OGF after dinner program.
