Erich,
I used conventional inner tubes (3-50 I think). You can cut them to length and superglue the cut end closed, thereby making an outer 3-sided chamber and a complete, folded inner chamber. Use a couple of wooden battens and G-clamp the ends together until the glue is completely set. Getting the valves in a comfortable place is the trickiest bit.
