I want to build a tunnel for a short film I am creating.
It would be made out of a white fabric, such as cotton. The tunnel would need to be 4M X 8M big, but I’m not quite sure where you can buy fabric this big, since fabric is usually only 2 metres wide.
I’m going to be shining light through it, so it will also act as diffusion. As a backup idea I was thinking maybe I could have 2 long walls of fabric, like a sort of hallway, but I would quite like to show the top of the tunnel.
Also in terms of supporting it; I was going to use 2 backdrop stands at each end and maybe a grip arm in the middle (the fabric would be clamped to these). But does anyone have any other budget friendly ideas for how to support it?
Does anyone have any ideas on how I can make this fabric tunnel / where I can buy a wide piece of white fabric?
