Alright, so I'm currently in the process of making a few outworlds. I've seen a lot of people make a "base" for their outworld, in which they would sprinkle sand, add plants and stones etc. And after receiving my "pinnacle" formicarium from TarHeelAnts which has the same feature, I figured I'd try doing the same thing myself.
Now, my question is: What do I need to do this? I currently have some Plaster of Paris and some soft natural clay lying around. Can any of this be used?
I also bought some (uncoloured) sand quite a while ago from Antstore, as I figured it might come in handy sooner or later. Should this be cleaned first, even though it states that it has already been washed? (I would assume that by washed, they mean cleansed by boiling water).
Thanks in advance! :-)
