5" by 8"- Eco smalti, dalles de verre, split pebbles
Originally, as I created this mosaic, I had the image rotated 90 degrees clockwise, so the red pulse line was on the bottom.  As so often happens, I discovered after finishing that I preferred the piece in this orientation.  But mostly, I really love the magic of cutting rocks in half with my hammer and hardie, which is an upended chisel with a mosaic specific mason's hammer. It's my all time favorite tool.
