I think the idea of having business cards available is a very good idea - especially with your booth location written in on it! - You might even have a tied down pen or pencil by the cards so people can write down what the item is that caught their attention.

I hate carrying a bunch of stuff around - and have trouble remembering where I saw a particular item - especially at a large show.

Maybe you could also advertise at your booth - "pay now, pick up when you leave" for items.

Advertise if you are willing to ship items later or have people come to your home to shop later.

I would be willing to buy the pattern for some items, even though I'm not willing to buy the item itself.

Examples: casserole totes, mug rugs, potato bags.

I also think it's hard to sell crafted items to other crafters.
