I just went to one. It was a delight to see all the creativity and innovative ideas. I was particular thrilled about one product I actually got for myself, as I found some items for Christmas presents and stocking stuffers. It has made a world of difference for me. So much so I contacted the knitter and asked to order another pair.
She was delighted that even remembered as she said, so many people take their cards but nothing ever comes of it. I have heard that a lot from some of the other vendors at many fairs as they roll their eyes at times, when you take a card instead of buying something. I may not need it now but I try to keep some of the delectables and artisans in mind throughout the year for gifts or personal items as they don't just sell at the fairs.
There was a particular instance of a man that made the most amazing salsas. I took his card as I was pretty well stocked at the time, a staple in my house

, and when got low a month or so later, contacted him and placed an order. He was surprised, pleasantly so, but that is a shame that some people think they can only get the products the fairs.
