How to thread at home

Hi Mona!

 I don't know how I can possibly thread myself. I thought one piece of the string has to be held by the teeth, the other by the right hand, and the other piece by the left hand?? I am trying out your instructions but I can't do it. Can you help? I really really need to learn how to do this. I am moving soon, and I won't have threading available there..and I truly cannot live without it. Thanks Mona
