Glossy Card stock
White Crayon (any color would actually work)
Some Dye inks
Stamp your image in a dark ink onto the card stock
Use the crayon to color in the area's where you would like a highlight to show
Soak some of the ink into the sponge and cover the glossy card stock. You can do this multiple times with colors, just change sponges.
Now you can use the paper towel to wipe the image. The ink will not stay on the crayon. You're done! Use it as an embellishment and put it wherever you like!
