The wood portion of this is the leftover part of a shield I cut for another project. It is just dipped in 50/50 BB. Red backer is 3/16" underlayment. The heart is 1/2" Poplar. The heart is the only thing that is scrolled. I shaped it with a belt sander, flap sander and a bit by hand. The shaping is very crude. It told me that I should never attempt intarsia. I abhor sanding!
