My newest shell is this 14 inch diameter by 5 1/4 inch wide curly maple shell.  I am still working on the finish.  It was made with a different technique than all my other shells that allows the shell to be narrower.  This one does not have a stand because it would tip over too easily if stood up on edge.  The smaller interior whorls are now partially exposed instead of being covered and the form overlaps onto itself.  The dark line is colored epoxy applied along the joint where the overlap occurs. This new construction technique makes the shell look a little bit more like the fossil ammonites that are the inspiration for the shells.
