Sure, why wouldn't you? Even as just a matter of courtesy.
You would tell them if you won a ribbon, wouldn't you?
So even if the comments ding the quilting, I'd pass it on.
Heck, you paid for it, you should let them know what the judges thought.
Mind you, some LA's have contracts where the fine print actually stipulates that you share the comments and if you win a ribbon, you must notify them in a timely manner.
