The craft fairs aren't run by the people at Elsecar Heritage Centre and at the end of last year there was some debate by the organisers about packing it in. I haven't heard anything from them since. The stalls were over £50 for the weekend so you had to get alot of sales, or one big one, to cover your costs and although the last few were busy for visitors they didn't want to part with their money. Mind you that seems to be happening pretty much everywhere at the moment.
