They look best with a textured surface. I have more than 200 trees based this way.

If you texture the tabs you can use them both on the edge and the top of tiles.The new tile tabs are going to be plastic. I suggested both clear and textured.

The clear tab is on the right.


The wall can be any shape so long as there is a square edge the dept of a tile along the bottom. So caverns should not be a problem. The texture or thickness of the tab will not be a problem.
The corners of the tabs should be cut at 45% so that they fit at right angles.
