...oh and the first thing that comes to mind...is 'cauliflower ears', dazzlenation...you see - the other day, I was to remember McGowan pointing out the 'collie-dog' plaque, on the front of his Clacton house...."find out what that is all about"...and at the time, I had simply figured 'quasi-collie'...McGowan, however - had figured that it was "more than that"...oh and 'crap taxidermy' had loved to box...he had been taught how to do so 'professionally' and by the british army...from an early age...see previous notes upon the 10 year-old, in the charge of ex-military headmaster 'montgomery' etc etc....go figure:

 

and so to cut a long story short...is your AI knitting program something around cauliflower ears?...and if so, it is not actually a 'hat' reference, is it?...what about 'ear mufflers'?
