Here is a short demonstration of weaving. I wanted to show you how threads become cloth.  Weaving is generally a two handed operation but I had my phone in one hand, so I was essentially weaving with one.  It’s not a very efficient process, however, and makes the cloth uneven.  This reminded me that my cousin Chana Lockshin Bob once asked me whether a woman needs one or two hands for weaving based on the following story from Masechet Gittin 34a. (text taken from Sefaria.com).

גידול בר רעילאי שדר לה גיטא לדביתהו אזל שליחא אשכחה דהוה יתבה ונוולה אמר לה הא גיטיך אמרה ליה זיל השתא מיהא ותא למחר אזל לגביה וא”ל פתח ואמר ברוך הטוב והמטיב

§ The Gemara relates: A man named Giddul bar Re’ilai sent a bill of divorce to his wife. The agent went and found that she was sitting and weaving [navla]. He said to her: This is your bill of divorce. She said to him: At least go away from here now and come tomorrow to give me the bill of divorce. The agent went to Giddul bar Re’ilai and told him what had occurred. Giddul bar Re’ilai opened his mouth and said: Blessed is He Who is good and does good, as he was happy that the bill of divorce was not delivered.

So as you can see, two handed weaving is recommended for many reasons!
