This will be my third year at the Tucson Gem and Mineral Show at the Tucson Convention Center February 11-14. Sarfish is one of the tables I'll be showing there. It incorporates a fossil starfish from Morocco.
I'm slowly learning how to create interesting shapes from the large slabs of Lyons Sandstone I get from quarries north of my home town, Boulder, Co. I got the right hand corner square. The left hand corner, not so square. The wonderful feature of the medium I'm using is that features like a non sqare corner can be filled in with black grout and do not detract from the design.
The picture below gives a better view of the starfish fossil and the "squareness"
of my stone work corners.
