The first is a problem, but that's the risk you face. The second isn't really a problem - so long as you have enough inventory that if you sell a reasonable amount of it you make enough money to justify being there.I'm nervous I won't sell much at all and equally that I'll sell out long before the show is over because I don't have that much inventory.
In other words if you want to make $500 for the day and selling half your inventory would do that, selling all of it early isn't a problem. You can give your stall space to the person next to you (they'll probably be quite happy about that), or spend the rest of the time marketing, talking about your products, and taking orders.
Being so popular you sell out is the problem everybody wants. That's not to say it isn't a problem, but at the same time it's the problem that isn't a problem, if you catch my drift.
Not many people will stop to look at a book. But some will. Almost nobody will look through more than a few pages. A few enthusiastic weirdos will if your product and presentation are good enough (nothing wrong with that). Basically if you have the time for the book and can do it affordably, there's no harm. They're a particularly good substitute if you can only bring a portion of your product range. But they're not worth making a priority.I'm thinking to make either a product book or some kind of flyer to show off all of my printed designs. I'm not sure if people will want to stop long enough to really look through the book, but not sure if a flyer will get through enough info.
If there's an idea you want people to take away (e.g. "Buy this featured shirt" or "We do custom orders" or whatever - your unique selling proposition presumably), then flyers are where it's at. But don't spend too much on them - many people will pick them up, yet never look at them.
Do keep us updated, and good luck.Anyway, if people are interested, I'll keep you guys updated on how things are going and how the show goes.
