Bas-relief is an ancient method to create three-dimensional imagery from a two-dimensional surface.
Line drawings depict three-dimensional images on a flat surface, however some might prefer to have these images extend into the round, becoming sculpture. An ancient sculptural method called bas-relief uses line drawings to delineate sculptural forms on a deep surface. A sculptor chisels away the excess material from the bas-relief, leaving three-dimensional forms within the envelope of the original material. Although bas-relief traditionally was chiseled in stone and wood, modern materials and tools, such as foam and rotary tools, can be used, instead.
Instructions
1. Draw or project your line drawing on the wood or foam panel. Use ink for strong, highly-visible lines.
2. Remove rough excess from the panel bas-relief with a rotary tool or chisel. Ensure the figuration in your drawing and design is not harmed by the shaping.
3. Carve the forms of your three-dimensional scene with the rotary tool and craft knife. Slowly and carefully, sculpt the material and avoid removing too much--repair of poor craftsmanship is difficult and time consuming.
4. Look at the bas-relief from different angles to find incomplete areas and inconsistencies as you carve the forms into the material.
5. Sand the sculptural form with the rotary tool and sandpaper to smooth surfaces of the bas-relief. Work slowly to avoid mistakes.
6. Sand the relief with super fine sandpaper to polish the surface of your three-dimensional image.
