Marsha, we have a local show every year, and every year people complain about the judging. I've been on or chaired the scribing committee for the judge for several years, so I may have a slightly different perspective than some. I think that long-armers and home-machine quilters *can* compete against each other. I don't know of anyone who would deny that Diane Gaudynski or Harriet Hargrave make masterpieces with their home machines.
However, I think dividing pros from amateurs is fair. Our guild defines a pro as someone "participates in quilting as a profession and for financial gain and/or has won a 'Best of Show' or 2 ribbons in any major judged show, excluding Viewer's Choice." Major shows are at least at the state level, on up through international.
I agree with this, though not everyone does.
Our guild uses certified judges. We do require that names be covered, but I don't really think it's necessary when using a trained judge. They have their preferences, in terms of style and technique, of course; but they do really try to be impartial and select the quilt(s) that best represent the category.
Bravo! If it's a joint effort, all names should be on the label. Anything else is simply dishonest.
If that's what your guild wants to do, there's absolutely nothing wrong with it! Go for it! :)
