the truth about me and craft fairs

Me and craft fairs are not getting on, I'm always in two minds to even do them as they are such hard work, and my products are not exactly pocket money stuff. So yesterday I packed my bags, left my house at some un godly hour and made my way to North London, I don't drive, so this involved 2 buses and a train, dragging a suitcase and two bags along. Now I really like the craft fair I attended, I like the people and the organisers, but I don't like the lack of sales. now I could take it on the chin, and say OK that was a slow day, but this is the 3rd craft fair in a row where I have made a loss or just about broken even, and I now have to ask myself, what is the point? I get great comments and feed back, I give out loads of business cards and lots of promises from people that they will DEFINITELY buy something from me....well they don't, and I spend five hours sitting. smiling and trying to stay positive, I watch people pick up every single item of stock I have and then put it down and walk away, that's fine, not everyone is going to buy something, but when at least 50% of the people at craft fairs happen to be other traders, then your not going to sell anything at all because traders will look and think they can do the same thing as you themselves. So I need to look at what I can do now, maybe concentrate on be stocked in baby shops, yes that might be a start,but today I'm going to sit down, pack away my sewing stuff and not look at it for a while.
