How to learn from a textbook?

Does anyone have any tips for studying from a textbook?

My old way was to use flashcards, but I am sooo sick of them. They can take hours to make, especially if I need a couple hundred of them and it's in a non-Latin script, like Cyrillic.

I think covering up parts and then trying to fill in the blanks could be useful. I've also tried making copies and cutting up different parts, then re-arranging them to make them more meaningful. But neither of these is a very organized way to go about it.

Does anyone have any tricks they've developed?

Thank you all for your ideas!! I'm looking forward to trying them out!
