It starts at 4pm. Tickets cost £12.50 and this includes a selection of finger sandwiches, home-made buttermilk scones with fruit jam and clotted cream along with a selection of home-made cakes and tea or coffee.
Stallholders are welcome and pitches cost £15.
Guests will enjoy entertainment, craft stalls and games on the lawn and the craft stalls are donating raffle prizes.
If it rains the organisers have a plan so it can still go ahead.
