Sewing On a Disposable Tray

Today I gave the thread and needle and a disposable paper tray, I marked and gave her where to insert the needle to give her an idea. Few days back I checked whether she could hand stitch on a cloth, but she could n't do it, she couldn't hold the cloth well and insert the needle. So just an idea came and thought of giving this tray. She was very interested to do it and she did it as per my advice. Tying the end of the thread , i did it for her. She took a bit time in inserting the thread into the needle, twice I just gave a slight hand support in that. But on the tray she did it without any support from me.
