This card uses a technique called "Grounding". See the shading under the hammer? Ot's what grounds the hammer so it's not floating in air. This technique is often used under the wheels of a bike or car, or under a person or object. See p. 59 (the vehicles), p. 82 (the robot), p. 89 (the dog), p. 92 (the animals), p. 103 (the chair, flowerpot and basket) from the 2009-2010 Idea Book and Catalog for other examples.
All it takes is a little soft suede or basic gray ink and a blender pen and you'll be "grounding" like a pro. Give it a try and post your comments!
