Make the Crafts and Make the Display, you will want to be thinking about how you will be packing your items up into your vehicle to get to the show. Some may be fortunate enough to have a trailer or a pickup truck, but most probably will be trying to fit everything into a mini-van, or a contained vehicle.
If you are doing a craft show farther away, you may want to either cut back the size of the items you make, or come up with some way to bring the items to the craft show. I've seen people pack things into a camper or into a trailer. I would hesitate to do anything very expensive for the first few craft shows. You don't want to spend more than you make, even at the beginning.
Start making a pack up plan, whether on paper or even just an idea in your head. I may take my ladders out to the truck some day and just see if they may fit. I'm a little less planned, so I'm just thinking about how things might fit. Even though I'm only going a few blocks away, I don't want to make a bunch of trips. We'll see.
