By the nature of the pattern, this type of wood looks like elm burl veneer: numerous small and large "eyes," chaotic fiber swirls, wavy lines, and areas where the fibers literally twist around the burl formations. This kind of irregularity works well on large furniture surfaces — the pattern is not perceived as ordinary parallel stripes of wood.
