The patches made of durable corduroy are a stylish accessory. They can be attached in three ways: iron on, sew on or use safety pins.

Corduroy (26% Cotton, 74% Polyester)
Attachment options: iron-on, sew-on and safety pin

Follow these steps when applying iron-on embroidery patches:
In general, the fabric you choose should be at least as heavy as the patch. Fabrics like denim and cotton work best for patches.
Place the item on a flat, heat-resistant surface.
Heat the iron to the highest setting your fabric can handle. Make sure the "Steam" option is turned off.
Iron the area where you want to attach the patch.
Place a thin piece of clothing over the patch.
Position the heated iron over the thin garment, and patch, and press down firmly on each side for about 25 seconds.
Remove the iron and let the patch cool.
Check that the patch is secure by lightly rubbing the edge with a finger. If it rises a little, repeat the process. For a totally secure patch, use a sewing machine or needle and thread to secure the patch to the fabric.
Full adhesive strength is achieved within 48 hours.

Note: Do not wash the item more than necessary as this may cause the patch to come off. If you do need to wash the item, hand wash it in cold water. Then let it air dry.
