Traditional exhibiting is a little convoluted to me. I don't have the patience to read through rules to get the perfect size or colour paper. This doesn't mean I won't in the future - just not in the traditional format.
Saying that, I always find the best displays at stamp shows are thematic ones that tell stories! Recently at the Brighton Philatelic Society in Melbourne, Australia, I read an amazing exhibit on Clara Barton - her amazing story was further enhanced by the wonderful display of Red Cross Covers.
