Halloween/Spooky Disco Decorations on Large Scale

It is a shame but in my children's primary school, the current Parish Priest feels strongly about Halloween and we are no longer able to have the fun of a disco for it anymore.

This is what we used to do. We made a lot of of decorations out of black bin bags as these cling to painted walls or you can use blue tack. Hissing cats, bats, spiders. A black crescent shaped moon with bats circling around looked good. We made Jack O Lanterns by cutting scarey faces in pumpkins and using tea lights in them. These were placed near the Tuck shop for health and safety reasons. We filled disposable gloves (got from Medical) with a red coloured squash and froze them. We had big round bowls (purchased from local cheap shop) full of red squash and the severed bloodied looking hands floated in them. We made full length black crepe streamers to hang down from the entrance door, and put spiders on them. We made 6 ft black skeletons, backed with reflective paper and purchased a lot of reflective Jack O lantern baloons which we hung on the walls. We got old white sheets from the charity shop and used these over a balloon to make several floating ghosts. We made a mummy out a cardboard lino tube and toilet paper. We covered the tables in black paper table cloths with glow in the dark spiders scattered on them. We also purchased a few sets of cheap fairy lights and hung them on the walls, so we did not have to use the main lights. We bought the spiders webs (about £1) and stretched it about to amke cob webs. A ball of black wool with black pipe cleaners out of it makes great hanging spiders.

I've used very large sheets of corrugated cardboard to make silhouettes of cats, haunted houses,ghosts, moon, bats, tombstones and pumpkins to decorate walls this year.
I got cardboard from skips around the local industrial estate, esp car showroom places, some are the size of big freezers
