I'm looking to cover a wall with a seamless edge-to-edge moss art piece like this:
This will be on an interior wall which I believe is plain drywall (any way to check it's not solid/concrete?), somewhat like the wall on the right in this hallway:
To avoid too much damage or difficulty removing from the wall, I was imagining getting thin plywood panels like this and attaching them to the wall and then gluing the moss to the plywood panels. I assume Home Depot can help me cut the panels to dimensions I need.
Is this a good method for accomplishing this? What's the best way to attach the panels to the wall? Can I use a nail gun or staple gun or do I need drywall anchors and screws?
