This is a terrific little display base you can make a diorama on. It is easy to make and it looks great.

I give you the template. All you have to do is measure and cut to t the parts then glue them together.

All you need is some cardboard and some glue.

The template for this project is right here.

Here is a look at the template. You make four cardboard sides and glue them together. Add four stops into the assembly. Then cut the top sheet and glue it into the assembly. For strength I recommend you make two sheets and glue them together.

Notice the dashed lines on all those side pieces. Those are partial cuts. You only cut through the top layer of paper and the corrugations. This allows you to fold the cardboard.

Let's build it

Measure out and cut the four sides. Put the dashed lines on the pieces. We will specially cut them in the next step.

Cut on those dashed lines. But.... only cut through the top layer of paper and some of the center layer corrugations. Do not cut all the way through. Leave the bottom layer of paper intact.

You have created a crease. Now you can fold along that crease.

Here is a side view so you can see how to bend it.

Glue those four sides together to form the base. A good tip is to first tape them together so they hold their shape. Then glue them. And after the glue is set you remove the tape.

Try to keep it very square.

Next cut some strips of cardboard that are 1/2 inch wide and glue them onto each of those four sides. These are a support for the flat surface we will put in.

Now finish it off by measuring, cutting and inserting the surface. I recommend you make two of them and glue them together for strength.

For additional strength you can add supports underneath the surface. I put one support. You can add more if your diorama will be heavy.

That's pretty much it. And now that you understand how it is made you can vary the size to whatever size you like. And it can be square rather than rectangular.

I used this exact base to make a diorama. If you would like to see that project it is right here: The Sardine Box Diorama.
