Clair and Others,
                             Clair, I do not consider you are a bumbling 
idiot but I can understand you may not be too keen to spend the cash and 
effort cutting from a 5 X 2 foot sheet an A4 piece of keyed Plexiglass 
before you can believe it works. It has worked for me over the past fifteen 
years. However, the paper will release early from the plastic if it has not 
been thoroughly cleaned of grease or if the sanding is not course enough. 
The paper can be re-stuck down if this happens.
                              I am continuing this thread with you ON LIST 
as it might prove to be a source of amusement and even a little education 
for List lurkers, but I am finding it difficult not to slide into my 
slightly sarcastic/facetious mode (see my past postings) as I cannot see 
what is  not to believe, for you.
                Just try it and see. If you find what I am saying is 
rubbish, please tell everybody and guard them against making a similar 
mistake. Then I will bow my head and slink back  into the shadows.
                                If you send me your mailing address OFF 
LIST we may be able to negotiate the cost for me to mail to you an A4  sheet 
of keyed Plexiglass plus cost of postage and packing, but, honestly, I would 
rather not.
                                 You cannot always trust what you believe, 
or not, in place of practical testing. Much depends on the imagination, of 
course.

Ciao and best wishes.

PS John Cremati's solution of a 300 ton press may not necessarily work, 
either ,unless you get the gelatine mix right.
