Okay my dear I will pay attention to the rules later. But I really like your well-organized instructions. I think you are enough to explain to beginners.

Our aunt has a Chinese duck at her house. So these structures look like that to me. So I have presented them as Chinese ducks. But your idea is right, it could also be a swan. But as far as I know, animals are very good friends. I am really grateful for your kind information. Thank you. But we will meet again.
