I was lucky enough to have received a block of Box elder Burl a long while back. While the main piece from that is still under construction, and having run out of pens kits I did a couple of stoppers from the trimmings. The cylindrical one has a Jasper in the top with a shadowbox effect. The other one is just plain funny...the coloring and worm holes are priceless . CA x4 and no knock down. Comments and criticisms needed
