Find all our Large Rocker Patches (Rocker means Arched patches that you can put on the upper or lower back of your jacket) with American Flag Embroidered ends. We do have them labeled as upper or lower patches, however that doesn't mean you have to go buy it. I've seen people put an upper rocker at the bottom of his jacket and a lower rocker at the top and it looked very original. So don't be afraid of trying something new and whatever you like is whatever you can have. You would need to sew these patches on to leather material, you can iron them on to denim materials. A lot of people ask if I can iron on a patch on to a leather jacket. The truth is you can, it will certainly work, but you will scorch your leather in the process too. Materials like Nylon and Leather don't like the heat too much. It's not a problem for our patch, it can take the heat and adhere itself onto almost any material as long as that material can withstand the heat you use while ironing it on.
