I am working on a 1980 450 SL and wanting to wrap the dash.  Ido not have a sewing machine so need to do this without sewing.  I am considering 4 way strech vinyl.  I have a general ideal but am not sure about what part to start on first.  do I start with the easy half, mostly flat with little streching or the hard part that requires the most streching?
Any pointers woulld be appreciated.
