Not really 'mercury fold'. STILL a fine fold with a dollop of 'lightning' folding.
(as most downloads are becoming) a VARIATION on a song.
A fine fold to WTF out
of...because just a
shuttle pass will not 'work' but once for an audience.
As one old
exponent who can actually do the mercury fold = over at least 30 decks folded and destroyed in a
lifetime of 'magic' - this method is A FINE method worthy of learning.
