On a bluish-purple background, paint giant snowflakes overlapping with one another as they fall through the air. Use a projector to trace your sketches of snowflakes on the wall. To add dimension and allow the snowflakes to stand out from one another, use darker hues to shade their edges, and give different snowflakes slightly different colors, like frosty blue, green and pink.
Create a scene with snowmen, snowwomen and snowchildren dancing, playing and singing, like in the storybook "The Snowman" written by Raymond Briggs and later made into a movie. This playful mural will lift everyone's spirits and keep them celebrating throughout the holiday season and beyond.
Paint a mural showing a particular habitat in the winter. It could be a local habitat or a perpetually cold place, like a tundra. Show animal tracks, burrows and animals hardy enough to brave the cold, like owls, cardinals and deer, depending on the mural's setting.
Paint old Victorian streets decked out for the holiday season, with lights giving the village a cozy glow. Show the people bustling about in carriages and caroling on foot from house to house. Leave out religious imagery if you prefer, in favor of glowing streetlights and rosy-cheeked children going home to warm houses for the night.
Paint a scene with children skating, sliding down a hill on sleds, throwing snowballs and doing other wintertime activities. Or, for a fun twist, paint polar bears doing all the same things, dressed in brightly colored winter hats and scarves.
Create a mural from natural objects with children or by yourself, as described on the Family Education website. Go on a nature walk and gather materials for your mural, like twigs, sprigs of evergreen, dried flowers, berries, nuts and any other natural objects you find. Then, arrange them on a large piece of paper or canvas until you're satisfied with their placement. The mural can be abstract, or you can use the materials to arrange a scene. Glue them in place, and hang on the wall after it dries.
Paint a scene of a white landscape lit up by the aurora borealis, the northern lights, beaming down from the heavens. If you're painting the mural in a school, it will spark children's curiosity about natural phenomena.
