Many of these stones will be larger that the common 30×40 oval stones. Some of the shapes will be inviting to that creative eye. Some are “just unusual” having no line of symmetry. You can “work” on these to give them that alluring look.
Because God has made so many different kinds of rock and he has provided me with many of them to work on; you will have many to choose from.
Take notes of those that “grab you” then carefully select those you can visualize a finished piece. Larry
