Instructions
Determine where the pin is going to be set. Pins are usually placed on the shirt above the left or right breast, on the tip of a collar and on hats. Be sure the chosen material is soft enough to be penetrated by a pin.
Remove the pin from its clasp and hold the badge in position above the material to make sure it is even. Carefully pierce and penetrate the material with the pin, going into and under the cloth, then make push it up out of the cloth. This is basically a stitch made with no thread.
Secure the pin back in place with the clasp. Straighten and adjust the badge so it sits comfortably and doesn't look awkward. If it is crooked, remove the pin from the cloth and repeat Step 2.
