Step 1: Measuring

Using a marker with yarn tied around it, draw a circle around the sheet metal also using the tape measure to measure how big or small you want the shield to be.

Step 2: Cutting

With the jigsaw,cut all around the sharpie line.

Step 3: Shaping

First with gloved on hands, bend the metal inward. Then, using a hammer hit around the edges and center until you get a half sphere shape.

Step 4: Spray Painting

Grab your blue spray paint, and spray it in the center. Tape the blue section off, then spray with red and do the same,then the next section with white.

Step 5: Star

When your all done, depending on what material your star is (my star was 3D printed) drill a hole in the center of the back of the shield and into the star.
