A. Stick On

Pressure Adhesive patches are like embroidered stickers. Just peel of the backing and stick onto a clean surface for a secure (non-permanent) hold. You can peel off the patch from a garment and use on another garment up to 4 or 5 times. Pressure Adhesive patches are popular for special events and promotional items. You can sew on a Pressure Adhesive patch to get a permanent hold.

B. Iron On

Heat Seal backing allows a patch to be ironed on to a garment. Heat Seal is a quick and easy way to get a secure, permanent hold with precise positioning. For those that don’t have time to sew on patches, Heat Seal is a great alternative. You can take heat Seal patches to a dry cleaner for professional heat pressing.
Or you can do it yourself using these instructions:

1. Preheat iron for five minutes on a high setting. Do not use steam.
2. Iron area of the garment where the patch will be placed for 25 seconds.
3. Place the patch on the garment.
4. Place a lightweight cloth over the emblem. Using a back and forth motion, press firmly     with iron for 25 seconds. Do not apply hot  iron directly to the patch.
5. Gently turn garment inside out. Using a back and forth motion, iron the back side of     the emblem for 45-60 seconds while pressing firmly.
6. Turn the garment right side out. Place a lightweight cloth over it. Iron edges to insure that they are properly sealed. Do not apply hot iron directly to patch.
7. Allow to cool thoroughly.

C. Sew On

Even with the development of adhesives that make patch application easier, sewing is still the traditional and most widely used method of patch application. Sewing allows for a secure hold and can be permanent with the option of removal. A sturdy patch can be removed and sewn onto other garments many times.

D. Rip On

You can also get velcro put onto the back of the patch so that it can be applied and taken off as many times as you like.
