To adhere this patch to your garment, you will need:

• An iron
• An ironing board or other heat-resistant flat surface
• Your patch
• A thin cotton cloth (e.g., tea towel or washcloth)
• A clean garment 

To apply the patch, you will need to:

1. Lay your clean garment on a flat surface.
2. Turn your iron on and set the temperature to the correct setting for your fabric; ensure that the steam setting is turned off and that there is no water in the iron’s reservoir.
3. Place the patch face-up on the garment and cover it with a thin cotton cloth.
4. Press down on the garment, moving the iron in a circular motion for 10-30 seconds.
5. Allow the patch to cool, then flip the garment inside out.
6. Cover the patch area with a thin cotton cloth and press with the iron for 10-30 seconds. 
7. Allow the patch to cool and check to see if the patch has adhered; if not, repeat steps 3-6.

While the iron-on adhesive should be strong enough to adhere to your garment for 50+ washes, sewing it on will make it even more secure.
