Changing a flat pattern to knitted in the round

Hi everyone,
I have so many great patterns that are printed to be knitted flat, seeing as how most of the things i knit i knit in the round because i prefer it i just want to double check. If a pattern is printed to be knitted flat all you do to convert to a knit in the round is reverse every other row right? So if every alternate row is like Purl you just flip it to knit, or if every alternative row has a combo of knit 1 purl 3 and stuff like that you still just convert it to purl 1 knit 3 right? I know this has been asked before. Thanks for your help.

This should help

Oh i didn’t even think about the row reverse! Thank you so much! No wonder it never worked when i reversed the stitches only! Thanks so much.
