What you need:

• Blender Pen -similar to an undyed marker, will take color from pastels and ink pads.
• Aqua Painter - a blender pen that you can refill with water.
• Watercolor Wonder Crayons
• Watercolor Pencils
• Stampin' Pastels

How you do it:

Stamp your images onto the cardstock.  Then using the blender pen or aqua painter, pick up a color from the Stampin Pastels by dipping the end of the pen onto a pastel.  Now apply the color directly to the image.  The blender pen or aqua painter will give you a watercolor painting look.
