Yeah, I second all the suggestions above. I bought plain white T-shirt bags and a colored sharpie. I write the name of my company on the bags and that works for me. You can also buy labels and print them yourself on your own computer. Cheaper than having them printed up. Avery has a template that is so easy to use, even I can use it. You just make up the label you want and print them, put them on the bags and voila! You're done.
You might also consider doing like a "lunch bag" that you can purchase in any grocery store or WalMart of KMart... places like that. Lunch bags come in brown or white, so buy white ones and print stickers. I wouldn't sell jewelry without putting it into some sort of a bag, so if you don't want to buy bags yet, just get the snack size bags and put the piece in those. Again, you can put your name on them with a Sharpie if you want to. Then put the baggie inside the paper sack and voila! Again, you're not spending much money and you have your name out there on two different pieces. It looks fine until you can afford to buy the personal stuff, and you'll look like more of a professional.
It's hard when you're starting, I know. You don't have much money for the little things that make your shop better, yet you have to have something. So think outside the box and make your own stuff for now. Buy plain and embellish, or buy a small amount.
And have fun at your first fair. Good for you that you're planning ahead. That's a really good thing!! Bet you'll do well.
