Veneer sliced across the log perpendicular to a radius is called flat cut or crown cut. Grain pattern will commonly produce arches, ovals, or hour glass patterns in the veneer.
Some species including many burls are becoming limited in availability and very expensive. Great logs may be available in some species, but sample material and lengths of hold are limited. Additionally, financial deposits may be required to extend holds beyond a few months. These logs should be considered for very special projects.
