Good to hear! My main concern is not doing anything artificial-seeming that disrupts the flow of the presentation, not the least because cramming a ten-card reading into a 30-minute session is already challenging enough for someone like me who likes to talk about tarot. I will do less of the visual gymnastics for someone who's experienced at sitting for readings because they could lose patience with the "window-dressing." The thought of it reminds me of a story I told here before about a dermatologist I once went to who interrupted my examination to go into her office and pull out a medical textbook to show me a diagnosis. Not exactly a confidence-builder.
I will say this about window-dressing though: the renfair crowd expects it. It's theater under those circumstances. I learned early on that it's the showiest presenter who gets the customers. And in the SCA it's considered a performance art. But I'm not good at hype.
In more intimate circumstances, though, I agree that window dressing probably just gets in the way.
