So how can you learn to create and place your own moss graffiti masterpieces? Well, WikiHow has a great guide. For starters, you're going to need to go outside and find some naturally-occurring moss. If you don't live near any, then you can also buy some live moss online.
So, find a wall or sidewalk and begin your masterpiece. Officially, though, we can't recommend doing this on any property that you don't personally own. Side note, aren't the trespassing laws in this country such a bummer?
As you check back over the next few days and weeks, you should see your mossy creation begin to grow and take form. If you live in an especially dry climate, you're going to want to bring a spray bottle to water it like you would a household plant. And throwing on a second or third layer of moss paint never hurts, either.
Once you've got the hang of it, you can create some really sophisticated designs. In fact, you'd be amazed what artists like Anna Garforth have done some using just buckets of watered-down moss and a paintbrush.
