When I published a photo of these great bluestones that I recovered from someone's trash earlier this year, a reader commented that he/she would lay them in a pattern with stones between. This sounded like a great idea to me. I've never done this, so I am experimenting. I loosened and racked the soil, laid the bluestone and then piled on extra dirt. After stomping it down and working in more soil under stones that wobbled, I swept the extra soil of off the patio. I'll gradually work in more small stones to complete the pattern. Its a work in progress!
