-I traced and cut out the blue (bottom) and red (top)circles same size and sewed them together (using the iron on glue works just fine) leaving a small space to stuff in some cotton stuffing (old pillow case stuffing works).
--The back of the shield can be fasten on to the dog with a strap of the same blue fabric and add Velcro to the ends.
-Then glued on the smaller white circle and then red circle followed by the blue circle.
-Finally draw or use a stencil of a star with white fabric paint. Let it dry for a day.
