Though I'm not very crafty myself, I've know a few people over the years who are, and just wanted to add a few thoughts, particularly about the price issue.
The cost of hand crafted items is obviously going to be far higher than manufactured goods. Not only are you using the raw materials in far smaller volumes (and hence more expensive per finished product), but the cost of the time involved adds up very quickly. I'd be surprised if a majority of craft-fair type goods, at full sticker price, even equal out to minimum wage for the person assembling them. I get that, and it's the reason I'd usually advise against selling crafts as anything more than a hobby.
With that said, it's also important to consider the potential buyers. By the very nature, many crafty items are a fairly niche interest. Most people who pass the booth simply aren't going to be interested in what you're selling. It's easy to write this off as people simply being "cheap cheap cheap", but that is kind of short sighted. Other than not saying it out loud, I don't see how that's much better than the non-buyer offering insulting comments in front of a seller... why can the seller insult someone who doesn't feel an item is worth the pricetag? Keeping in mind the niche market of the items, pricetag is what it is, but value is only in what someone is willing to pay. The same people who refuse to purchase at your booth may be the same ones who happily drop a pretty penny at another booth for something that catches their fancy, and vice versa.
More importantly, when people aren't interested in buying the product (at the posted price tag), it would be far more productive to ask oneself why that is. Part of the issue, no doubt, is that money spent at a craft fair is pretty high on the pyramid of discretionary spending... well after things like coffee on the way to work in the morning, etc. Most customers don't have unlimited funds to spend, and may tend to be more careful in their purchase selection. That in mind, what makes your product special or unique? What makes it 'better' than the generic mass produced equivalent at
Walmart? Who is the likely audience that might be interested to purchase? If the answers are "anyone would love this" (said with naive cynicism), "it's special because it's hand made", or even "I really don't know", then that might be part of the problem. If the goal is to make any money by selling items, that makes it a business, and as such, you have to think about it like a business.
I would highly recommend the PP suggestions of using etsy... unlike a local craft fair, it has two main advantages: it provides a much larger target audience, which helps overcome the limited appeal and "niche" factor. It also tends to attract more people who are actively looking for a specific kind of item, rather than just those who are browsing in the hopes of finding something that looks interesting.
