Slate entry

So I laid out some tiles to see how they would look, I have a limestone surround edging the existing area , I can either take it out , which I think I will do , however I was thinking of another option of doing a simple inset of the same stone a thin banding perhaps ? Just thoughts.

I actually decided to take out my hammer and chip out one tile , I hit it really hard and nothing , I suppose I can wait for the weekend to make that mess, huh!
