In this tutorial, we learn how to use foam to make diorama terrain. Foam will make a realistic diorama because it comes in so many different shapes and sizes. You can buy this from hobby shops and even online. To put these together, you will simply use some wood glue. You can easily cut this with a sharp knife, scissors, and anything else that is sharp! You can use a hot wire cutting tool to mold and sculpt the foam as well. You can also use a hot glue gun to connect the pieces of foam together and make an object. Have fun and get creative!
