I recently got this tile sample by Stone Impressions, and while it's not right for the project on which I'm working, I was quite taken by it. The detail is incredible! I wish I knew more about pattern design and tile fabrication. It's definitely not hand painted, but how do they get such fine detail?
My thing is that I just like the one tile.... as a field it's a little too much; you miss out on the tiny dots.
Or maybe not... see 4 tiles here.
