I second what Don Teach has said about using rubber cement.  It needs
to be a 50/50-percent solution.  The best product I have found is
the one made by Union Rubber Inc, out of Trenton, New Jersey, the
Premium Best-Test White Rubber Paper Cement and the thinner Bestine.

Of course be sure to finish the surface with talcum powder.  If you
aren't concerned with a budget you can skip this step altogether and
use the Morton Red extra-extra-thin leather from Columbia Organ
Leathers.  It doesn't require sealing.
