I've just spoken to Neville at the factory about this and he says
he'd want to see a couple of inches overlap if the BID is applied in
2 pieces. The overlaps should be positioned clear of the hinge
reinforcements and offset so as not to lie on top of each other. His
preferred method, though, is to cut the BID rather wider than
specified, and stretch it gently to the length required (which will
of course make it narrower again). No doubt one could work out the
"prestretch" dimensions required to get exactly the right result, but
best to err on the side of too wide rather than too narrow, I think!
I'm posting this partly to check if the list server is still working,
as it's gone suspiciously quiet since 1st January.
