you must set to "linen", not wool. you need the hottest you
can get.
use a paper towel between the iron and the paper and you
may iron until the paper yellows. do not apply too much
pressure and insure you move the iron so the holes don't
copy.
iron long enough so the board heats up well and uniform.
drop the hot board into luke warm water and gently lift the
borders so water get under the paper and releases quicker.
