If the product you choose comes with a buoy or float then you can easily attach the flag to it. The product will most likely come with instructions, and you can also find help online. The majority of flags can be attached by tying a rope through their two grommets and attaching that to a pole. If the flag does not include a buoy or float, then you can attach it to one of your own, or you can tie it to a pole attached to a boat.
