What do you like to call yourself?
I prefer seamstress because the first adjective that springs to mind with the word seamstress is somehow “clever”.
Sewer ? Nah… Sounds smelly
Sewist? Sorry not a word
Tailor? Too daunting. One would be too presumptions to call oneself that as yet. Besides it has no nice feminine noun
Couturier? Hm…. Like the sound of that.
