There was a another part of the stencil that was for edges. I should have shown this better, but I am going to do the same stencil today on the pad I made a video on last week so I will film that part.
Wow, this looks really good. My front garden path is made up of concrete slabs set in gravel. I've been wondering how best to give them some interest, and stencilling looks like the answer. Thank you!
