Continuous Line Drawing
A continuous line drawing is one in which a single, unbroken line is used to develop the image.
Aside from the fact that a continuous line drawing can be a work of art in its own right, it is also a worthy drawing exercise for developing hand-eye coordination and observation skills
Parameters for making a continuous line drawings:
Once you place your pen or pencil on the surface, do not remove it until the drawing is complete. Your goal is to describe the subject with one, singular line. It can become thicker and thinner in areas, but it should never break.
Try to move your hand at a similar speed in which you observe the subject with your eyes. This will help to create more accurate proportions and shapes. But remember, perfection is not attainable.
Do not erase. Leave the imperfections and let them be a human element in your work. (As humans, we are attracted to artifacts that are clearly made by other humans.)
Repeat. Do several drawings in one sitting and try different tools. You may find that you are more comfortable completing the exercise with a graphite pencil instead of an ink pen or vice versa.
Wire Drawings: Continuous lines in 3-D
Continuous lines can be used in 3-D art as well using wire of various gauges
Instructions:
Making a 3-D wire portrait is really easy. All you need is 18 gauge wire, pliers, tape, plastic page protector or transparency, and a print out of a photograph of yourself or someone you know
Place your printout in the page protector. It is easier if the photograph is a side (profile) view
Use the 18 gauge wire to trace the outline of the facial features.
Use tape to hold down the wire
Use the pliers for the hard angles to be able to twist and shape the wire as you need.
Once finished remove pick up the wire portrait and remove the tape
Place your 3-D portrait in some sort of stand or vase
