I've never done a craft fair or anything, but from what I've heard, and from the potential customers point of view:
If you already sell your stuff on eBay, let people there know that you're going to be at a Fair. Those who lurk but never buy may actually buy, if they can get up close and touch things.
Maybe share a table or something with a friend who does a completely different type of thing, you'll attract twice as many customers. Or push your tables together. Or branch out your self into other crafts, but I think someone else already said that.
Like everyone said, I wouldn't even bother with the shows that aren't just for handcrafted things.
Just some suggestions..
But I reckon for your first show you did really well! $60! That's pretty good, you know, that could go towards the table for your next show!
Wow, your husband sounds really nice too..I want one just like that!..Maybe you could get him to make some stuff, too? If he does woodwork or something?
