Anna's story reminds me of my own DD, and mades me think of a time, not long ago when I was shopping in the sale room through a collection of Nancy Halverson fabrics & needed some lights in a very medium collection. Another customer stopped by, critiqued my choices, pulled my "lights" out & offered another medium, said my choices didn't "go." Shocked, I just said, that well, now, I just strongly disagreed with her, at which point, she promptly looked at me, paused, and told me to have a good time picking fabrics, turned around and walked off. I thanked her kindly.
Picking colors is like talking about the certain topics that aren't allowed on quilt forums. I do listen carefully to the pros talk about color and value, but life is too short to be using fabric combinations that hurt our teeth.
