I would use natural ledgestone(3"x6" 4" thick approx..) for a border around the flagstone pathway The width of the stone should give you enough seperation and the thickness of the stone should keep it stable You could use rocket pavers (type of direction paver) but real stone would look awsome, you will find if you use anything smaller than a 1/2 " crushed stone the average shoe will track it everywhere,
