Here's an idea for creating snowy pictures with salt and paints - it's a fun experimental painting technique for kids to have a go at and it creates an interesting effect.

You will need:
Paint a wintery scene.
Leave the paint to dry until it is tacky rather than wet. Sprinkle salt over the picture and leave to completely dry.
With a dry paintbrush, dust off the loose salt. Some of the paint will come off with the salt and some of the salt will stick and you will be left with a mottled snowy effect.
