If you don't want to watch the video read on.
So today I am going to tell you what you need to make a miniature ruin. First you need to get some paint brushes, get a fine tip paint brush that is still a bit thick, get a medium sized paint brush, and a large paint brush.
On to the paints, you need to get 4 main colours, white, black, dark brown, and mustardish. There are several other colours, yellow, blue, green, red, and orange are the ones you need, try to get at least two shades of this colour.
A bubbly type of foam is required, as you can just use your fingers to shape the ruin out.
Always remember, be resource full, and never buy miniature ruins.
