Option1: shows the steel strip edge against the tile and lawn letting the garden come right up to the pavers, this is a very tidy way of doing it. Steel needs to 100 x 6mm. In my case to get a step for the mini golf the steel is 200x 6mm.
Option 2: shows the concrete 100mm wide concrete strip if the top of the concrete has a bevel it lets the lawn have some dirt to grow in.
Option 3 : allow angle fixed to old surface easy and very tidy.
