Rainy Day Mum has some brilliant ghost decorations.

Or how about some pipecleaner pumpkins?

Make a Halloween garland like Tinkerlab. You could experiment with different materials to see which moves the least/most in the wind.

If you don't fancy carving a pumpkin, this yarn wrapped pumpkin from The Imagination Tree is lovely.

Decorate your room with some fake blood and learn about coagulation at the same time.

We love these spider web paper plate decorations from Creative Family Fun. Another idea is to make the web sticky and throw spiders at it.

Halloween Party Food

Serve up jelly scabs for dessert. These look gross but taste delicious!
