We keep a rotating stock of pine Live Edge Slabs and fir/larch Mantels. The slabs start at 1 1/2″ and go up to 5″ thick. The mantels can be up to 10″ thick. With the 1 1/2″ and 2″ slabs there may be some twisting that happens through the drying process but everything thicker than 3″ has been resawn to a flat surface.
