Q "Do Nuns make a Habit out of making their own clothing...?"
Some say that Nun is more Heavenly and like Mother Mary than a Sister who listens to the Sin-cere ad-Vice of her Father and takes a Vow to make a Habit of donning a Cassock in the best Convent-Shun-all style, every time she Confesses to spreading some oil on the Friar in the kitchen.
You know, it's dark humor like this that I religiously avoid, so it's nun of your business what I think of it, Sister. How long has it been since your last infection? You can't just convent jokes and think that superior mothers will like them. I pray you will take a vow of silence and take pity on a poor soul such as myself, because Lord knows I am no saint. I will sin you a sign, an omen, if you will, to tell you you're really preaching to the choir on this one, and that's the gospel truth. Go now, my child, you owe me fifty male hairies (don't EVEN ask me what those are). ~
Back in the days where Nunnung was a big thing the popular culture firmly though that young girls should be kept busy at all times. "Idle hands do the devils work".
Today. in museums, you can find many large historical tapestries resulting form that. Usually made by some Noblewoman and all the girls she could command, the below is scene 37 of the Bayeux Tapestry (it is Looong :)
