I haven't done it at a big show, but I have been a white glove lady at local shows.
I really enjoy doing it even though it means a lot of time on my feet. It's an opportunity to look at quilts up close and really see the detail, and see other people's reaction. It gave me the chance to talk to different people, too. I turned quilts up so viewers could see the back, and made sure no one was touching the quilts.
I've never been compensated for it, other than maybe getting a quilt pin. And if I lived closer to Houston I'd be there in a heartbeat!
