Matching Between Adjacent Veneer Leaves
It is possible to achieve certain visual effects by the manner in which the leaves are arranged. As noted, rotary cut veneers are difficult to match; therefore most matching is done with sliced veneers. The matching of adjacent veneer leaves must be specified. Special arrangements of leaves such as “diamond”
and “box” matching are available. Consult your woodworker for choices. The more common types are:

Book Matching
The most commonly used match in the industry. Every other piece of
veneer is turned over so adjacent pieces (leaves) are opened like the
pages of a book. Click to see PDF of illustration.

Visual Effect - Veneer joints match, creating a symmetrical pattern. Yields maximum continuity of grain. When sequenced panels are specified, prominent characteristics will ascend or descend across the match as the leaves progress from panel to panel.

Barber Pole Effect in Book Match
Because the tight and loose faces alternate in adjacent pieces of veneer, they may accept stain differently, and this may resultin a noticeable color variation. Book matching also accentuates cell polarization, causing the perception of different colors. These natural characteristics are often called barber pole, and are not a manufacturing defect.

Slip Matching
Often used with quarter sliced and rift sliced veneers. Adjoining leaves are placed (slipped out) in sequence without turning, resulting in all the same face sides being exposed. Click to see PDF of illustration.

Visual Effect - Grain figure repeats; but joints do not show visual grain match.

Note: The lack of grain match at the joints can be desirable. The relatively straight grain patterns of quartered and rift veneers generally produce pleasing results and a uniformity of color because all faces have the same light refraction.

Random Matching
Veneer leaves are placed next to each other in a random order and orientation, producing a “board-by-board” effect in many species.

Visual Effect - Casual or rustic appearance, as though individual boards from a random pile were applied to the product. Conscious effort is made to mismatch grain at joints. Degrees of contrast and variation may change from panel to panel. This match is more difficult to obtain than book or slip match, and must be clearly specified and detailed.

... that managed forests, thanks to their high proportion of young, strong, growing trees, enable CO2 to be extracted?

... that an old, unmanaged forest produces as much CO2 through processes of decomposition and decay as it stores, and that therefore an unmanaged forest contributes nothing to reducing global CO2?
