Yes, you can harden a felt hat using a few methods. One common approach is to steam the hat and then shape it while it cools, which can help to firm the felt. Alternatively, you can use a fabric stiffener spray or a mixture of water and white glue to coat the felt, allowing it to dry completely to achieve a stiffer structure. Be sure to test any method on a small, inconspicuous area first to avoid damage.
