How sad! I hope she didn't discourage your group member into leaving or giving up on quilting. I adore going to show-and-tells and seeing newcomers quilts. It takes a lot of courage to get up in front of people - and you never know what issues they may be dealing with (arthritic hands, etc). That "Quilt Police Wanna-Be" should be ashamed of herself!
Every quilt is a labor of love.
