Plus here's a great idea to liven up the surroundings for your prehistoric party! Why not make some paper maché boulders? Just scrunch up some big sheets of newspaper and then cover them in at least two layers of paper maché. (Remember: paper maché is just strips of old newspaper pasted on with a mixture of PVA glue and water in equal quantities.) Once the paper maché has dried, paint them in shades of grey and brown to look like real boulders! Or how about a collage dinosaur head to peep around the corner of a window? Cut out a dinosaur head from thick card. Scrunch up balls of tissue paper and glue them on. Paint in dinosaur-like colours of your choice, and remember to add gleaming teeth and big eyes.
