   Alan,

   There are many kinds of grafting tapes that can retain the moisture 
of a graft union.  People have been known to use masking tape and other 
such products that should moisture seal the graft. Parafilm will also 
breath as it does in its usage in the medical world where wounds do 
better with exposure to air.  Question is, does the Parafilm have any 
advantage over other grafting tapes because it allows air to reach the 
graft union?
