stepping stones yet again

Ok, so the dear husband and I have agreed on doing simple stepping stones for now with the option to add gravel in the future. So our stones will be flush with the ground and have grass growing around them. Like this photo except I am planning on using irregularly shaped flagstones.

 We're also doing a stepping stone path alongside the edge of the house, leading from front yard to back. I figured we might as well buy all the stone at once!
