If you enjoy decorating your clothing and accessory items so that they stand out from the pack, then you should definitely look into using iron on patches to help you accomplish this task. There are a number of different designs you can pick from. If you are more interested in humorous sayings rather than intricate designs, you can find plenty of those type of patches as well. Your biggest problem will most likely be finding the patch you want in a size that will work for your purposes and narrowing down the list of patches you really want to use. You only have so much space on your jacket, sadly.
One of the best things about using iron on patches is how easy they are to use and the fact that they can be added to just about anything. It doesn't even have to be clothing. For example, if you have a plain purse and you want to spice it up a little bit, you can easily attach a few different patches to it. Or if you have a plain baseball cap, you can easily put a patch in the center of it right above the bill and then share that sentiment with the world.
The reason that iron on patches are so easy to use is that the back of the twill patch is coated with a specialized heat activated adhesive. This means that when the temperature gets to a certain degree, the glue bonds with the material. Usually these patches are attached easily within thirty seconds. It is important to note that you can't use iron on patches with leather because the heat from the iron will damage the material. That and the fact that you can't remove them and reuse them later are the only drawbacks to this type of patch.
