Glueing Moss

I have previously glued moss to a thin piece of filter sponge. I used Seachem Flourish glue in lines. The glue dries white, so can be visible, but when the moss grows and is trimmed it becomes more bushy and covers any glue marks. I'll also say that I had more success with the moss I cut into small pieces and dabbed onto the glued sponge, rather than trying to attac individual strands of moss.
It looks untidy to start with, but after a few trims the moss looks fine.

I'd say that they were around 1cm apart.
