grease or oil applied to the pages in certain aeas where some transparency is needed, then fixed/sealed onto it with something,rather that cutting out the paper and putting in transparent plastic-- technobadger, Feb 02 2002 Does paper that's been greased stay clear after it is dried? If it does then croissant (the companies who make the transparent paper/plastic won't like this idea though).-- NeverDie, Feb 02 2002 It does stay translucent for a long time - cheap windows used to have oiled paper in them; you couldn't really see out but you had some daylighting indoors.-- hello_c, Feb 03 2002 Some artists I know use that in their places-- thumbwax, Jul 24 2002 random, halfbakery
