Lazy Net Question; Catching up with Flashcards

Language study expands and grows. Yes, I know all studies do that.

Premise: I've only studied 3 languages formally, and never used/created my own flashcards in any of those classes.

Latin is growing and picking up speed. Not finding that a problem as yet. Problem is how to incorporate flashcards as instructor recommended: not only does the information line lengthen, as more vocabulary is added, but conjugation and declension "widens" that line of knowledge.

For instance, in the first two small chapters, it was the introduction of 1st declension, all feminine nouns and adjectives as subjective complements, then demonstration of nominative and accusative cases. All verbs were 3rd person singular, mostly all first conjugation.

Add more words, including 2nd declension nouns, mostly masculine. All nouns are still singular.
Boomlet: more nouns, soon to add neuter, now with prepositions and ablative forms, add plurals, add more stems. Verbs in 1st, 2nd, don't forget plural....

So, when making a flash card for a word, say a noun. On the front of the card I'd put the the root form? The basic word, singular? On the back just the definition? Or definition and all the cases that I know so far? Write tiny so that I have room to add more cases?

Or I presume make new cards for all the past words when we learn a new case?

What was your strategy for language study?
