Grain
A person who begins woodcarving is challenged to learn to work with the fiber and grain. Hardness and fragility vary with the species of wood. In general, wood tends to break in the "split direction", the direction in which the fibers separate. In the composition of work, one must work with and around this. Each direction of cut feels and works differently. Sharp tools are essential in allowing the artist's sense to shape the material.
Planks of wood are said to be quarter-sawn when the growth rings are more or less at right angles to the thickness. If the growth rings are more parallel to the width, then the plank is said to be slab-cut. While slab-cut planks are seasoning, they tend to cup in a direction so as to "straighten" the growth rings.
Seasoned wood never completely stabilizes, but continues to swell and shrink with seasonal humidity and temperature variations. Any design concept using wood must allow for the particulars of this dimensional variation. Warped wood may be described as bent, twisted, or cupped, or some combination of those modes.

Famous quotes containing the word grain:
“As polishing expresses the vein in marble, and grain in wood, so music brings out what of heroic lurks anywhere. The hero is the sole patron of music.”
—Henry David Thoreau (1817–1862)
“He showed me that the lines of a good helve
Were native to the grain before the knife
Expressed them, and its curves were no false curves
Put on it from without.”
—Robert Frost (1874–1963)
“Indigenous to Minnesota, and almost completely ignored by its people, are the stark, unornamented, functional clusters of concrete—Minnesota’s grain elevators. These may be said to express unconsciously all the principles of modernism, being built for use only, with little regard for the tenets of esthetic design.”
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
