Question: fun things to do on a rainy day for 12 year olds?
Answer: Cheap art and craft supplies. New colouring and activity books. Pencils, textas, crayons and chalk. Old make-up and your latest wardrobe throwaways for costumes. Jigsaw puzzles. Old magazines and newspapers for papier-mâché or collages. Left over party favours like balloons and decorations.
