Consider every jot and tittle
Every minor detail. A jot is the horizontal mark on the letter "t", and a tittle is the dot above an "i" or a "j".
Also from soup to nuts
Also, from A to Z or start to finish or stem to stern . From beginning to end, throughout, as in We went through the whole agenda, from soup to nuts, or She had to learn a whole new system from A to Z, or It rained from start to finish, or We did over the whole house from stem to stern. The first expression, with its analogy to the first and last courses of a meal, appeared in slightly different forms (such as from potage to cheese) from the 1500s on; the precise wording here dates only from the mid-1900s. The second expression alludes to the first and last letters of the Roman alphabet; see also alpha and omega. The third comes from racing and alludes to the entire course of the race; it dates from the mid-1800s. The last variant is nautical, alluding to the front or stem, and rear or stern, of a vessel.
As noted, also from A to Z, from start to finish and from stem to stern.
