A tiny favour

Jan isn't what you'd call an earth mother.
She doesn't knit her own yogurt or stuff like that.
A few days ago, for only the third time in 16 years, I asked her a small favour. If she could ever find her sewing kit (because I don't possess one) could she please complete a very small repair for me.
I'd been tempted to get smart and use a stapler but, not wanting to damage my unblemished skin, I thought better of it. Anyway as she toiled and sweated at my small request she reminded me of a famous painting which I can't quite place at the moment. Maybe it was this one?
