Here’s how to do it: Set out a large protective surface (I used poster board). Spray the back side of the patch and fold the top and bottom to the back. Press firmly and hold in place for a few seconds. There is supposed to be a 1/8” blue frame all around the dots (or diamonds) so measuring and ironing it first would help with accuracy.
Spray the back again and fold the sides in pressing firmly for a few seconds with your fingers.
Carefully following the regulations, spray the back again of the now-folded patch and press it down in the proper place on the uniform.
Stitch around the edge and you are done! If the side has flared a bit and there is some fabric sticking out from under the patch, use a pin to tuck it back in while you are sewing.
The can of adhesive spray was $12.95 and worth every penny. I sure wish I had thought to buy a can the day my son became a Civil Air Patrol cadet officer!
