I'd have thought there would be an application form somewhere on the folk week website.

If this is a genuine question, and if the pitch costs are too high for you to make a decent profit, then no, I wouldn't bother applying.

However given the tone of previous threads on the subject, someone far more cynical than me might suspect that this looks rather like an attempt to get just one more good Sidmouth-bashing thread in before the end of the year.

So have fun y'awl ...
