Looks great Turtlehead. I like how the moss is growing on the rocks as well.
Do you mind sharing your technique please? Especially what you used to set up the moss in the beginning, ie those square things? I'd like to try a Moss groundcover like that myself! Also, why did you choose to use Taiwan Moss instead of Willow/Java Moss? Was it just what was available at the time, or because they grow differently?
