Gather you materials...
~salt (large grain, like kosher, or sea)
~towels (for all the inevitable messes)
Use your black crayon to draw out a simple winter scene.
Paint your picture using generous amounts of water.
Sprinkle salt on all the areas of the painting you wish to look frosty.
Leave the salt on the painting until it thoroughly dries.
After several hours (or the next morning) gently wipe away all the salt. What is left behind is a glittery salty frost effect. It doesn't photograph well (for me) but its absolutely lovely!
We've had such a great time trying out this new technique, I hope you enjoy this too!
