thick cardboard

For the custom C8 focus-mask, I was thinking I'd use some cardboard from the back of a notepad. But that stuff is usually about 1 mm thick. It would work but it wasn't quite what I was after. Not quite sturdy enough.

Today, I stumbled across a thick sheet of cardboard in a random pile of paperwork. Wondered where it came from. A calendar? A photograph?

Anyway, at a thickness of 2 mm, it would be perfect for the focus-mask plate.
