My best results are with paper card such as used for mounting photographs. I have had excellent results with 1.4mm card (my original prototype!) and recently 1.0mm card.
To keep them flat I made a 3mm perspex support, as can be seen in this photo.

Hi George,
I thought about the same solution but not with acrylic support. It would waste a lot of acrylic and it's quite expensive. MDF will be much cheaper. The only problem is that the whole mask will suck in water from air and it will bend eventually and loose its shape.
