I made the guard tower first, fun project as it was using simple blocks. I designed it to break in half for easy transport and to have 2 terrain pieces.
I then made up the ruined tower and another piece inspired by the ruined tower.
I ended up selling all of this stuff to fund some more molds. I have about 30 molds I think at last count.
I then made up some Sci Fi inspired terrain and sold it as well! Here is one piece out of 10 as an example.
Some of the casted blocks.....Fantasy and sci fi
