Print out your snowman template.
Colour in your snowman's hat. I've used a black marker but you can go with whatever color and design you fancy.
Pour some white paint onto your plate.
Dip your q-tip into your paint and colour in the snowman using dots made by this.
Once the paint is dry you can add some details to your snowman. Using a black pen draw in your snowman's eyes, mouth and buttons. I'd recommend a Sharpie for this as it draws well over paint but as they're permanent I know they're not always the best choice with young kids in which case a chalk pen normally works as well and is less likely to stain.
Cut a triangle out of orange card or paper and a scarf shape from coloured card and glue these on to your snowman to finish your craft.
