So the statement does clear up if the name and stitching were from a single participant
... and in two instances it was stitched over by other participants ...
In two cases the contributions of participants to a collaborative artwork were defaced (and arguably had their meaning reversed) by other contributors.
I'm not sure from the statement, are the NT confirming that they had seen this defacement and still decided that they would put the artwork on display?
Is it that the NT saw that the defacement had occurred but decided that the message delivered by the damage was more important than that of the original author?
Jean Hatchet's narrative of what happened puts the blame for stitching over JKR's name at the feet of two trans identifying NT members of staff.
If this is the case then why are they simply referred to as 'participants' in the NT statement. Surely this piece of information is very relevant to the story
Perhaps the original author was a 12 year old girl, carefully stitching the name of her favorite author. Maybe the NT decided that she needed to be taught the life lesson that her voice is less important that that of an adult male who wants the rest of the world to affirm him in his fantasy that he has become a woman?
