Watercolor pencils have to be one of our favorite media. They have the convenience of colored pencil, but the coverage of watercolor paint. Below are some basic techniques for using the watercolor pencil. If you think of others, leave a comment, and I'll add it to the post.
Watercolor Pencil
1. Activate with water. Simply color down the watercolor pencil and paint water over it. The key is to lay down a lot of pigment, and then paint the water. This allows the color to be rich and to spread a lot.
2. Activate with watercolor paint. Color the watercolor pencil down, and instead of clean water, use watercolor paint. Use a different color to create interesting color blends.
3. Activate with watercolor marker. Color the watercolor pencil down, and use a regular marker, such as a yellow Crayola, to color over the watercolor pencil. The marker picks up a lot of pigment, and this technique will eventually ruin the marker. But they're inexpensive.
4. Dip in water. Dip the watercolor pencil into water and draw or color with it. You may need to repeatedly dip the pencil in water, but it creates a rich color with a slight texture.
5. Draw into wet paper. Paint either clear water or some watercolor paint onto a page, and then use a dry pencil to draw or color into the wet paper.
6. Layering. Use any of the above techniques, and allow it to dry. Then use another color with the same or different technique on top. You can build several layers of watercolor pencil for a page with richness and depth.
7. All-at-once. You might not have the time or patience for layering. So, color several colors at one time, and blend with water.

8. Sprinkle watercolor pencil shavings onto wet paper, and smear with a finger.
9. Color with the dry pencil, spritz with a water bottle, and leave it to do its thing.
