It's too easy...

Go next door. Pick up moss ball. Plop on thing....Kokedama kusamono. (Moss ball, grass thing)

Sweet! Gotta appreciate the simplicity of moss as an accent.

I have a thing for moss as well.
Though only one of mine looks like shaggy hair. Much shaggier than your moss ball. Lol the other two I took Serio's suggestion of finding moss in sunny locations. Which makes it very tight short compact moss.

Great!
Now do it with a small tree in the moss ball.
Keep it alive and thriving for at least one season, maybe two.

... just to make it not be so incredibly easy.

Got to begin with seed.

I see little Doug Fir seedlings pop-ups in the thick moss every spring!
