Grant,
He thought it was crazy to attempt making a dextrine coated paper at
home. I tried it several times and agree with that: the paper is all
shrunk up and there is now way for a hobbyst to make it flat and
straight. Pulling out a home made dextrine paper out of a laser
printer is a nightmare I will never forget. I admit that idea behind
it is simple but the problem is to dry the coated paper so it looks
like paper you and me know. Mike
