I have been engraving stone since 2002, hard to believe. I engrave Name and Address Markers, Garden Stones, Fund Raising Bricks, Stone Signs, Gifts, Awards, and a variety of other products. There's always something new and interesting. I have also written a 150-page manual to help teach others how to do this. The first 3 chapters are on my website in the "Biz Opp" button.
