One of the most important tools

No matter what kind of carpentry work you are doing, a hammer is probably involved.

Notes: With this drawing I begin work on constructional, perspective renditions of everyday objects. The real homework is this image, where you can see the pencil-lines of the planes, boxes, and cylinders, in perspective, of which the hammer is built:

The pencil lines are erased, and more shading and contour added, to make the final image. The key thing is that the perspective is different from the reference image, because we're not just recreating an image, we're building an object from primitive forms. My next few drawings will likely be similarly simple in their final form, while I practice this constructional method. (Okay, you didn't really want to know any of that, I know.)

Materials: printer paper, mechanical pencil, very cheap eraser, Staedtler pens
