English woodcarver and educator Chris Pye has written several books and online guides to woodcarving, including his Woodcarving Fundamentals. (If you’re not interested in woodcarving specifically, stay with me here.) There and elsewhere he describes the woodcarving concept of “bosting in”, the stage in which the carver establishes the relationship among the various elements of the carving, before carving any details.
To ‘bost’ means to create the main forms, three-dimensional masses, and planes of a carving; and placing them, with their inherent motions and directions, all in correct relationship to each other.
Chris provides the example of a student attempting to carve a human face. According to his process:
Before the iris goes in, the bony shape of the skull, the muscles, the egg-like lump of the eyeball and so on, these must be formed, bosted in. The shape, dynamics of the head must ‘read true’ – that is what the bosting is all about.
I like this example. It’s both familiar and immediately illustrative of the concept. What he describes here is not working from a blueprint. It is an approach to creating that engages the senses and skills of the creator throughout the process.
“Bosting in” falls within the larger process he describes in his book, Elements of Woodcarving. This process begins with roughing out the waste, followed by bosting in, followed by modelling individual elements, and resulting in detailing.
Chris has stated that he would like to retain the term “bosting” as a specialized term within woodcarving. I think he’s on to something more broadly applicable in the creative process, so I’ll use the more generic term “sketching”, which he says is the original meaning of the word.
This strategy of “sketching in” – establishing the masses, planes, and movement of a piece – works in many different applications.
I see it at work in Jim Krenov’s The Fine Art of Cabinetmaking, in which he describes composing a cabinet from the starting point of a coopered door. “Since I have gotten into such work, the prospect of returning to it each time I find a ‘beginning’ in a plank or planks is ever more exciting.”
As a writer I’ve used a similar process, leaving myself sketches of an idea that needs elaboration, while establishing the overall flow and movement from one idea from another. During later passes through the piece of writing, I’ll come back and elaborate on each of these sketches, gradually giving definition to the whole.
I’ve even used this process as a software engineer, roughing out the various components, sketching the basic movement of the application, and gradually working it down to finer and finer detail.
