is a 12x12 puzzle possible and if so, any idea where I could find details on creating one?

Thanks !

is a 12x12 puzzle possible

if you mean a box-size of 3x4 (a 12-squared puzzle),
there are examples at menneske.No

the Pappocom software can generate puzzles of this size --
use: menu - Type - Rectangle

if you mean a box-size of 12x12 (a 144-squared puzzle),
see this --
... and, for my next trick, 144 x 144
