I guess I'm lucky. I've been quilting over 15 years now, and have run into only one person who might possibly be in the quilt police. And during that time I've belonged to 5 different guilds in two states, attended probably close to 100 quilt shows, and associated mostly with other quilters, who have been both supportive and helpful. Some people have urged me to label my quilts, but I don't think of that as quilt policing. It's just someone telling me that my work is worthy of acknowledgment. And I agree that I should label my quilts, just as I agree with my doctor that I should lose weight...
The one person who might be in the quilt police? That was a lady I overheard at a quilt show, explaining to her male companion that the quilt they were looking at was more easily made than he might think, because the dense quilting had been done on a longarm. After they left I got a closer look and found it was actually hand quilted!
