Hello. Would you please explain the underlined part?
According to the writer, she thinks the artistic values of the Tapestry was great, but craft and narrative trump concept, abstraction is not geniune or something?
Also, I want to know what "craft" means in this context below.
Thank you.

I first saw the Bayeux Tapestry in photographs, when I was 10 years old, in a 1966 issue of National Geographic magazine
that commemorated the 900th anniversary of the Norman Conquest of England.
But oh! This Tapestry! This was sewing-this was art-on an order of magnitude that I had never imagined.
And now, almost 40 years later, I can say that I learned all my core artistic values(craft and narrative trump concept, abstraction is a sham) from this piece of linen.
