That wasn't the quilt police...that was a wannabe quilt snob...the quilt police have taken classes...this girl was just wanting to act like she knew it all.
I would have sat her down...and asked her to draw me out what she felt was a "proper quilt"...including color choice, etc...and do a block to show me what she meant. She would have ran out that door...probably never sewed a stitch in her life.
Dislike people like that...and have a few in my family.
