What aesthetic problem can bow and crook in a log cause in veneer?

• A. It can cause the cathedral pattern in flat sliced veneer to run in and out of the sheet.
• B. It enhances symmetry in veneer sheets.
• C. It has no effect on veneer quality.
• D. It improves dimensional stability.

Answer: (A)

Bow and crook introduce curvature in the log, which changes how growth rings line up when you slice it into veneer. In flat-sliced (plain) veneer, these rings form cathedral-like arches. If the log is bowed, the position of those arches shifts along the sheet, so the cathedral pattern can appear to run in and out of the veneer. That creates an irregular, visually noticeable pattern across the sheet, which is undesirable for veneer quality. It doesn’t improve symmetry or dimensional stability; instead, it disrupts the uniform appearance that veneer aims to achieve.
