Thanks D6.

Yeah, I was trying to get the grass all they way to edge but for some reason it wouldn't stick- not sure why. It's possible I had feathered out the adhesive to such a degree that it had already started to set when I started sprinkling the grass. It is much more noticeable in the pictures than when you are looking down on them on the table.

The tile adhesive is very strong so the shrubs stick pretty hard. Even so, I know that the odd one will pop off here and there; I expect that I will occasionally have to do repairs.
