In this tutorial, we learn how to make mud and rubble in a WW2 diorama. You can use corks as the rubble after you paint it and rip it into different pieces to make it look like destroyed buildings. You can purchase realistic water and gloss gel medium to look like water that is on the battlefield. If you mix them together with some chunky material, and then add in brown food coloring, it will look like mud. Using these tips and tricks, your diorama can look more realistic and look fantastic! Decorate the diorama how you want, then enjoy taking your time and doing a great job!
