Thank you very much for the replies, dear Orchidsoul and Sayna. I appreciate how quick you both were. I feel consoled and reassured. I will read your posts over and over.
Please allow me to ask a more question. When I described what I had named "curtain clamps", was my poor English understandable? Do you know what we use? Perhaps the word "clips" would be better?
I thank again for your helpfulness. I am very happy with your answers. I certainly got more tranquil. A very hearty and very humble thank to you.
