Beautiful plants! I love staghorn ferns. So unique. For the smaller ones that I have in terracotta pots, I use wire orchid pot hangers so I can hang the pot up. You can purchase them or make your own with coat hangers. You clip them to the lip of the pot and due to the center of gravity the pot will have a tilt that sort of mimics it being mounted, making it easier for it to have it's right orientation.
