While many bikers like to cover their jackets and vests with patches just for decoration, there was a time when patches were mainly used to repair old clothing. Some people still use them for this purpose. Most use plain colored patches that closely match the original material so that it's difficult to tell where the patch is, but you don't have to do that. In fact, bikers often use brightly colored biker patches to cover rips and tears. This gives the piece of clothing a whole new look and can be used to take something that's looking a little worn and give it new life.
Pants eventually wear out, especially if you're hard on them like bikers can be. If you have a crash, for example, chances are you're going to rip a few holes in your jeans. You could go out and buy new ones, of course, but what if they're your favorite pair? Plus, breaking in new jeans can be a pain, and sometimes, it can even be difficult to find pants that fit right. If possible, why not repair them? Since patches come in all shapes and sizes, you should be able to find one that fits over the rip. Just iron or sew it on and your damaged pants are ready to be worn again!
You can also use patches to turn a pair of older pants into something new and different. This is a great way of covering up stains or spots that look like they're about to wear out. You can also add patches to pants to personalize them. Of course, patches can be used on more than just your pants. You can add your own personal touch to belts, hats, shorts, and even things like cloth grocery bags.
