Bikers love to buy new gear and motorcycle related items. Some people buy biker stuff all the time. They see something online or in a store and pick it up. Others only buy biker related items at rallies or when they happen to see a really good deal. It can be a lot of fun to buy yourself some fun new biker gear, especially if you haven't treated yourself to something fun recently.
If you haven't filled up your biker jacket, you can buy yourself as many new patches as you like until it's completely filled up. Just remember to make sure you've got the space by measuring the black areas on your jacket before you buy. You don't want to end up with extra patches and no place to put them, unless you enjoy collecting patches or what to put them on other items. If you collect patches, you don't even have to look at your jacket. Just keep buying them and adding them to your collection.
Some people do replace the patches on their jacket every now and then. These bikers buy new patches at major events. They might change up their Sturgis patch, for example, each year they attend that rally. Or they might want to change up all their patches every now and then, so they buy new patches every year or so.
Other bikers pick an event or a certain time of year to add or change a patch on their jacket. For example, they might decide to get a new patch every year on their birthday. Some bikers decide to exchange patches every year for Christmas or on Veterans Day. You can add new patches whenever you want. It all depends on how often you want new patches.
