A3 tracing paper body, transparent acrylic frames in the back. I was only able to get A3 size 160 g/m² tracing paper, so I have to join some of them to make bigger screens.

Current idea is to have 5 normal screens, 4 big ones and 1 long – one on each side.

To be on the safe side, I need to get about an acrylic sheet of 1×1 meter and 1 or 2 mm in thickness.

(26*2*2+23+ 23*4+26*4+ 26*5 + 26*4 + 26*8 (or *4 if 1,2 meter) = about 765 mm)
