I think this would be a fun project to try with your kids if they are out of school already.
Stamp your image in Black Stazon on Glossy White card stock.
Color in some areas with your Whisper White Watercolor Crayon, some other light colored Watercolor Crayon or a regular crayon.
Apply ink to the entire piece of card stock using a brayer, sponge daubers or a sponge. Where you applied the crayon, those areas will resist the ink.
Use a tissue to wipe off any excess ink.
Then you can go back and color in the areas you masked off with the crayon if you wish.
Try it! I bet your kids will have fun trying all sorts of combinations!
