Is there a supplier that sells some kind of metal reeds or grasses? I have two Ruddy ducks that are swimming and I need something to put them on. My original idea of a stump with some roots sticking out, to attach them to, just isn't coming together. Can't seem to find the right one! Just trying to come up with another option. Would like to find something flat and wavy to come from under their bellies to set them on.
