From this month’s edition of The Craftsman Newsletter:

Second was the encounter with textile artist Rachael Matthews who introduced Noguchi to the use of darning mushrooms, a tool for mending and not a hallucinogenic substance. The view of a sweater that Matthews had patched up time and time again using colourful yarn challenged Hikaru’s understanding of repairs. Until then, she believed that you had to make the damage become invisible, the repaired object needed to look like brand new. Hikaru started darning her own clothes.

This seems like a way of maintaining clothes but also a way of maintaining oneself.
