My head is spinning with all the questions asked.
I can answer a few for you.
If there are multiple judges, they all judge all the quilts. They tally the scores and the one with the highest wins. I like when there is more than one judge. The main reason I like to have multiple judges is that they all may have something they really look for, another one may really like something else. Having more than one, just seems to level out the
playing field. I LOVE reading the comments. You can learn tons by those comments. Most judges are very kind.
Some judges are announced and others are not. I do know that if they end up with a tie - they can get down to the nitty gritty and do some measuring.
I do keep my comment cards to make sure that when I enter another show, I know what I really have to work on.
It is great fun to enter quilts and see what happens. You never know!
