Entering a quilt show should be fun. I look at it as a learning experience. Good judges give a good comment or two, then a comment on how it might be improved. Even if I know that one block was wonky, that's something they can say in the comments.
And what one judge says should be changed, the next judge will say that is the best feature on your quilt!
So let it all go and just enjoy looking at everyone's quilt and they will have fun looking at your's
