I wonder, if you painted your design, in reverse, onto a piece of paper, could you then use that like a transfer by just pressing it onto the surface you wanted to beautify? It would be quicker than painting it in place, but I don’t know it it would transfer enough gel to work effectively. If you could leave the paper in place for a while it might work quite well.
It might be quicker to use stencils, but that’s a great idea. I wonder if it needs to be the wet state for it to work.
Could potentially work, you’d need something that grips the moss paint enough to hold the design, but not more than the wall surface. That’d be tricky.
I knew a couple street artists who pre-printed all their work, they used wheat paste to slather it onto back alley walls and painted over top. If you used a cheap, recycled paper that decomposes just a little slower than the moss roots in, that could work to just glue it in place.
Stencils are my personal go-to.
