You will need:
Large sheet of gold card
Yellow, red and orange tissue or crepe paper
Brown paper or card
Cut a bonfire shape from card.
Cut flames from the tissue paper and glue them to the card. Try not to glue them flat but bend them and only stick bits down to add texture and make the flames look more real.
From brown paper cut some rectangular "log" shapes and glue these to the bottom of the fire. Finish off by taping on some real twigs to bring the collage to life and add even more texture.
