Initially, we must establish the dimensions of the bricks. For this instance, they are intended for use in a 1/24 scale diorama, making them 24 times smaller in size compared to real bricks.

I began by measuring and marking the vertical lines using a fine-tipped marker pen. Then, I switched to a semi-sharp pencil to draw the lines. It's important not to apply too much pressure to avoid damaging or tearing the foam.

Once the vertical lines are established, I proceed to draw additional lines every other line. Next, I revisit the grid, positioning the ruler between two adjacent vertical lines, and draw along the unmarked spaces in between. This technique helps create the desired "shift" effect between the bricks.

Once all the lines are drawn, use a blunt pencil to go over each brick, enhancing their visibility and dull the edges.

Grab a piece of aluminum foil, shape it into a ball, and then firmly roll the ball over the foam to create small indentations.

Affix the thin foam onto a sturdy base such as cardboard to provide structural support for the wall. Be cautious with the type of glue used, as certain adhesives can cause the foam to melt. Cut out openings for windows, doors, and other features as needed.

Start by applying a primer to the wall, followed by dry brushing it with a lighter color. Make sure to accentuate the lighter color in the crevices. Then, proceed to paint the wall with random shades of browns, reds, or any other colors you prefer.

Finish by applying a dry-brush technique using lighter colors.
