Ray Bates asks about suppliers of zephyr, stating that the German
supplier mentioned previously only supplies in 2 metre squares.
I suggest he contacts Herzog, who I recommended recently:
http://www.lederfachhandel.de/ 

They sell zephyr in three thicknesses, including the 2 thousandths
thickness he requires, and sell it in at least two sheet sizes,
the smaller of which is about A4 size.  I have never heard of zephyr
being made in anything like as big a sheet as 2 metres square.
There must be an error in translation somewhere.
