my my such a can of worms is the issue of paid for quilting.
As to the judging. If the quilt is not in a two person,group or duo category then the judge never knows and it is judged as one entry/piece. However, a judge quickly begins to recognize the same quilting. How it is entered is up to the show committee. I often wonder if a quilt is assumed to be made by one person and there are comments about the quilting (done by another) if that quilter ever knows what the comments were. Unless there is a category for duo quilts then it is up to the one who entered to indicate details about the quilting. Judges never see (well almost never) what is on the entry form. We might sometime ask for the title of the quilt, but to me that is about all we should ethically know about the quilt. I will add that sometime I might ask if the quilt was made by a young person so additional encouragement can be given.
