Thanks,
I got some shelf fungus on the other side,
didn't show it because one of them fell off
and there is just a wire sticking out where I fastened it.
Oh, and I got into the habit of just making mushrooms
with any extra green stuff I had left over from a project.
and just threw them in to my bits box for later.
one last thing....
I believe I just used small bits of wire for the stems.
Edit: oh wait you meant the big one,
those mushrooms are Styrofoam chunks glued to the side & covered on plaster..
