It depends on what my space is whether or not I take everything. At several shows, I only have a 6ft or 8 ft table and others I have a 10x10 booth. When I have smaller space, I choose a good representation of what I make and take that with me. I'm always afraid I've chosen wrong and not taken what would have sold, but it's just too difficult to take it all, plus with only one table I can't fit it all underneath. I'm learning at repeat shows which types of journals typically sell, so I may take more leather or vintage. With new shows it's hard to gauge.
At shows where I have a larger space, I do take everything. I stash lots under the tables and I always have people who want to go through all the tubs and find just the right gift. I make one of a kind items, so I can't display it all on the tables. When I pull the tubs out for customers, other people seem to become interested as well.
