Size of stepping stones
I don't have a Japanese garden -- it's more of a native New England woodland garden -- but someone on the Gardening with Stone forum suggested I post this question here:
How big should my stepping stones be?
I've done lots of research but I can't seem to find much on this subject. I'm using flagstone to create a winding stepping stone path through my yard -- total length about 110 feet. I've dug out a trench 8 inches deep and 40 inches wide. I plan to add five inches of gravel, then place smaller round stones as edging, then add two inches of sand, then place the stepping stones and level them, then fill in with soil and start growing moss. The only reference that mentioned size said the stones should be at least 18 inches wide and 3-4 inches thick, and should be placed with the longest side across the path, not along it. (G. Hayward, Garden Paths.)
(The latest input from the Gardening with Stone forum -- 12 inches wide, 25 pounds minimum, 4-6 inches thick, but preferably stone should weigh as much as person stepping on it. 200 pounds?)
I have yet to see a design that resembles mine -- most stepping stone paths don't have stone edging, or any edging -- but I have several reasons for doing it this way (which I'll spare you unless you think it would be helpful).
Any advice appreciated,
