Here is another guest post from : http://alisaburke.blogspot.com/2012/03/creativity-with-crayons.html
"Think crayons are for kids? Think again! There are all sorts of great ways to use a box of crayons in your art- here are a few ideas...
Go back to the days of coloring books and use them fill your drawings with color-
Use them to create a resist with watercolors.
Start by using a white crayon to draw on a blank page.
Paint over the top of the designs with watercolors
and watch your designs come to life!
While your paint is still wet, press it onto another page and make a light print- its what I call a 2 for 1 deal!
It makes a great background for journaling!
Go wild with abstraction and scribbles!
Fill the page with colorful scribbles.
Use watercolors to fill in the white space.
Tip- use paper as a background for journaling, cut it up and use in collage projects, scan and use in digital projects or doodle over the top...
Use crayons to create colorful rubs. Rub over surfaces with texture.
Use in backgrounds for mixed media projects.
