We do a game called 366, you write all the days of the year on envelopes have a number of star prizes and others are free burger, free piece of cake etc. Charge 50p or £1.00 a ticket.
People buy their birthdays etc, we always have a few Christmas Days.
We are lucky and generally get a voucher from a few local restaurants.
Decorating biscuits is always good, your local Tesco may donate them for you.
The Bar B Q always makes the most money. You can hire one, but ask your local church, scout group if they have one.
Also pimms or beer tent. A licence is about £25.00 from your local council.
A bottle stall is good if you get kids to bring in a bottle, booze, vinegar, sauce, pop, bubble bath etc.
We also do 'jolly jars' kids bring in a jam jar filled with something and decorate it. Sweets, coloured pencils, chocolate buttons, stickers, those Cabdurys bit size things etc. We generally say bring in a Jolly Jar as payment for a dress down day.
We have also done, bush tucker trails where the kids were blindfolded and had to put their hands in buckets behind a screen to fish out ping pong balls, the buckets had custard and baked beans etc in, kids LOVED it, BUT DO THIS ONE OUTSIDE!
