(1) you do not need a grille. What you do is take, say,
20 numbers, like this: 7, 3, 2, 4, 5...
Which give you the number of nulls you write: 7 nulls,
one true letter, 3 nulls, one true letter, 2 nulls, and
so on. Look: no grille!
(2) you cannot use a grille to decrypt your text, because,
as you said, you wrote a draft first (using a grille)
then copied it with the lines sagging right. Result:
apply your original grille onto that and what do you
get? Gibberish, because the positions of the "true"
letters no longer match the positions of the holes
of the grille.
